become successful. Also, we're trying to reach our first 1,000 subscribers, so would appreciate a sub. So, firstly, I needed to find a game idea, and I landed on this game called Be a Snake. You start off as a small snake, then you
Speaker A
have to eat food to become big enough to eat other snake bro. But I wanted to be a bit more creative and make something more like Slither.io, where rather than eating the snake, you have to outmaneuver the opponent to eliminate them. So, here we
Speaker A
are in Roblox Studio, and the first thing we're going to do is connect the Roblox Studio MCP to Claude Code. And I already did that, but I verified with Claude just to make sure, and Claude says it's ready to go. Next, we're going
Speaker A
to head into Claude Design to create our first 3D model of a snake. And we're going to click this 3D object option here. And then we're going to type in a prompt of how we want it to look. And
Speaker A
after a few iterations, here is our beautiful looking snake. So, we're going to save this as a GB and save it to our folder. Now that we're back in Roblox Studio, we're going to click on the import button up here, and we're going to
Speaker A
grab the snake that we made in Claude Design and click import. Then wait for the import to finish. And look at that, he's made it into Roblox Studio. So here we're back on Claude, and we have Fable 5.1 loaded up as well as setting it to
Speaker A
high mode. And what we're going to do next is create the prototype for our game. So, what I did here was I pasted in a prompt where I explained the actual game itself, as well as ways we can
Speaker A
monetize the game, whether it be buying skins, buying revives, etc. So, I'm just getting clarifications with Claude first. So, Claude just made us a playable prototype. So, we're going to test it here. And here we have the game
Speaker A
itself. Here's this is just the lobby, but the actual game is here. Look at that. It contains all these different eggs. You can hatch different skins and stuff, as well as the leaderboard. This is just a placeholder leaderboard. We
Speaker A
have the daily reward chest here. Here, it's going to we're going to design that in Claude Design separately, as well as the daily spin. So, let's actually hop into the game here. And this is the actual game itself. As you can see on the
Speaker A
settings here, we can change between WASD and mouse. We have a fully functioning prototype already. This is insane. So, you basically just collect the pellets and then you try and outmaneuver the snakes to kill them. We can even see on
Speaker A
the leaderboard here who is on the top of the leaderboard, as well as a mini map down here. So, we're back in Claude Code, and while Fable 5.1 continues working on the bugs and other gameplay mechanics, we're actually going to start
Speaker A
a new chat here. And then I asked Claude Opus 5 for what we should be doing while Fable 5.1 continues working on the gameplay mechanics. So here we can work on making the game passes, as well as all
Speaker A
the different models like the snake skins, pets, lobby props, cosmetics, and all the other stuff that we need. So we're back in Claude Design, and while Fable is working on the gameplay, we designed different skins for the players
Speaker A
to be able to roll if they purchase different eggs. So here we have the dragon model. Here we have the skeleton model. Here's the cobra model. Here's the shark model. This is the Mecha model. This is the zombie snake model.
Speaker A
And here we have a cute cactus model. Additionally, I also created this spinner for free spins, as well as this chest for dailies. So, here I imported the models directly into Roblox Studio.
Speaker A
And as you can see here, we have everything ready to go. Now, I'm going to just tell Fable 5.1 to put these where they belong. Then, we should have different snake skins people can roll for. I also optimized the game further
Speaker A
so that it's much smoother, and the bots are actually much smarter as well. The game at the current state is very fun.
Speaker A
It's very playable, and it's actually insane how fast Fable 5.1 can get the game rolling right off the bat. We also added a death screen where you can play again and go back to the lobby, or you can revive your snake for 50% of the
Speaker A
length if you watch an advertisement, which Roblox actually added this as a feature a while ago where we can also generate revenue when players watch ads.
Speaker A
So here I'm on ChatGPT to create some UI for our game, and it created some awesome looking UI. So we have the spinner here, the coins, and I did some revisions on the shop UI, as well as the rebirth and
Speaker A
codes UI, and it looks fantastic. So we're going to import these back onto Roblox Studio. So, here we got Fable 5.1 working on implementing all these UI icons, as well as fixing some bugs that I ran into, such as when we go near
Speaker A
the eggs, the UI that pops up that's supposed to show all the different things you can roll for is a little too large. And when you go near two eggs, both of the UIs collide with each other. So, we don't want that to
Speaker A
happen either. And any of the UI buttons that we click don't have any content inside of it. So, we got to fix that as well. The kill feed also covers most of the UI buttons right here. So,
Speaker A
we got to put that on the bottom left corner. All right. So, Claude has placed all of the icons, as well as fixing a lot of the bugs. And now we're just talking about the game passes and dev products
Speaker A
that we're going to add. Now, let's take a look at the actual game. And we now have all of the content inside of the UI able to be seen, as well as the daily login. We also have that coin
Speaker A
animation. We have the shop available. This still needs to be a little worked on, as well as some of the dev products and the game passes. We're going to work on that as well. We have the rebirth.
Speaker A
We're going to work on this page as well. So, what I'm going to do, I'm going to give myself a bunch of coins. Okay. So, I got a million coins from my code. So, here we have the egg
Speaker A
gotcha system all ready to go where we can get the skins. So, we're going to roll one here. We even have this hatching animation that plays as you roll. And wow, that actually works really good. So that's awesome. We also
Speaker A
have the playtime rewards working. So players are incentivized to play for a duration of time to get these rewards they can unlock. So if we click this one here, you see coins drop like this. So the players can actually pick them up if
Speaker A
they walk on it. We also have our free spins button up here available. And this needs to be worked on a little bit. But if we spin here, oh, we got a skin.
Speaker A
That's cool. That's cool. One more time. And we got our coins. So we also got the coin animation going. All my skins are also available to wear. So, I can just choose a dragon snake here. Let's go inside the game. And look at how good
Speaker A
this looks. Oh my God, this is genuinely insane. Look at the fluidity of the movements. There's no lag whatsoever.
Speaker A
And these bots are doing so well. This guy's trying to get encircled. So, we just have a few more stuff to touch up, but other than that, this is all working super well. And I'm just really surprised at how fast we can get a
Speaker A
Roblox game going using AI. So, now it's time to redesign our UI panel. So, we got Claude to generate all the prompts that we need for all the different UIs, such as the shop, backpack, daily spins, playtime rewards, group chest, rebirth,
Speaker A
and you get the idea. And we're going to paste these images into GPT Image 2 to get us our desired UI designs.
Speaker A
So, here we're back on ChatGPT with a giant prompt that Claude gave us to paste in. And it gives us all the descriptions of what we need, as well as the respective dimensions that it needs to follow. So, you can take a look here
Speaker A
with all the different prompts that we have. And then it generated these beautiful looking UI designs. So, th
Speaker A
And this is for the egg hatching screen. And this is for your death screen. So, we gave all these different backgrounds to Claude and it's going to implement it for us. I didn't label the images or anything. So, I'm just seeing if Claude
Speaker A
can figure it out on its own. And it would be really cool if it can. So, Fable 5.1 implemented all the UI here.
Speaker A
And it looks good, but the sizes are a little off. So, I want the UI more compact, meaning there's no extra space here because it's a little too spacious around here. As well as the Playtime Rewards background. There's too much
Speaker A
room around here. So we want that to fit perfectly around the edges of this actual content itself and so on for the daily login or any other thing. So we're going to get it to fix all of this and
Speaker A
tighten the background to match the content inside. So what you're actually seeing here is GPD6 Astra are using computer use in codec to actually resize and fit all the UI so that it's all compact and no text or any buttons are
Speaker A
poking out of the actual UI backgrounds itself. And you might be asking why I'm using GPT6 Astra for this instead of Fable 5.1. Simply put, I like Codex's computer use much better, and it can generate images whenever it needs to, so
Speaker A
that's a plus. So, here's the results. Codex made everything fit nicely together. Nothing's poking out or anything. Everything's fitted inside. It even stretched and resized all the UI to make everything fit inside neatly. And Codex even added these different frames
Speaker A
for our leaderboard or our mini map. And even the portraits of the snake, it looks really good overall. And even the death screen, everything's compact and nicely fitted. The UI overall looks really good. I think there's a little
Speaker A
bit more work I need to do, but other than that, the game is basically good to go. I just need to rework the lobby and some of the map, including this door over here, and then the game's good to
Speaker A
go. I can just start advertising, seeing if the players join, and then see the retention score. And then, if the game goes good, I can just continue updating, adding more skins, etc. Also, a last minute idea, I found this cool VFX pack
Speaker A
from the creator store, and I'm going to implement these inside of the game as well for the players to be able to roll and equip them for their snakes [music] when they're boosting. So, here I'm back on ChatGpt and I generated all the game
Speaker A
pass icons as well as the developer product icons and it's good to [music] go. I just downloaded all of them and we're going to start making our game passes and dev products now. So, here I'm on the page where you create game
Speaker A
passes and I'm going to create my first game pass. So, we're going to click create pass and the first game pass [music] I'm going to create is 2x coins where players get two times the amount of coins they would usually get when
Speaker A
playing games. So, I just uploaded the icon and we're going to name this double coins and then we create the pass. And then I'm going to repeat this entire process for all my game passes as well as developer products. So here I've
Speaker A
uploaded all the game passes as well as setting the prices [music] and for the developer products as well.
Speaker A
And now what we're going to do is copy the ID of each product and we're going to send it to GBD6 Astra to implement.
Speaker A
So here I'm back on Codex with this giant prompt that I'm about to send to GBT6 Astra and it includes all these different sounds as well as some bug fixes and all of the auras that it's [music] going to implement for us. And
Speaker A
we're going to send it now and I'll get back to you guys once it's finished. So Codex has finished and implemented everything we needed from all the UI buttons to other bug fixes. And we also created this new lobby area which looks
Speaker A
absolutely clean which we actually got Codex to build the entire lobby from scratch. We just asked it to generate us some concepts and we went with the pocket carnival version here which looked really nice. And we just sent it
Speaker A
this giant prompt that included some bug fixes and some other features that we wanted added as well as the prompt for it to actually build the map itself. And we told it to use Matt Schumer's gauntlet loop to actually build the map
Speaker A
which is a clever loop which spawns a bunch of sub aents to actually verify the builder AI's output. And with the fresh context from the sub agents, it's actually able to direct the builder AI to stay as accurate as possible to how
Speaker A
we want it to be built. Also, for brand new players, we added this new tutorial system for better onboarding for the players to actually learn how to play the game. And the first instruction for them to do is hatch the egg, which
Speaker A
they'll be given free coins to hatch their first basic egg here. And the egg hatch works perfectly. We added all sorts of new UI. The floating hover UI is all working as it should. All the portraits of the snakes are in place in
Speaker A
the hover UI. We also added the proper odds of all the snakes they can earn.
Speaker A
And the next step of the tutorial is to actually open your backpack and equip the new snake skin that you got. So, [music] we can wear it here. Everything works as it should. We also added a kill sound effects menu where players can
Speaker A
actually purchase these sound effects with coins, which these sounds play when you eliminate another player. So, something like this. [screaming] Also, if you get eliminated, you can hear the other players kill sound effects. We also added a boost sound
Speaker A
effect where when you boost the snake, it actually [music] plays these sounds. So, there's a bunch of different ones you can choose from. We also have the auras menu where you can actually roll for auras using this aura box right
Speaker A
here. And we have all sorts of different auras you can choose from, which I'll showcase when I get into the game in a second. We configured and placed all the UI to where it should be. We even made
Speaker A
the shop menu much cleaner. And as you can see here, all the game passes are set up and ready to go, as well as the options to gift other players or your friends. We also cleaned up the rebirth
Speaker A
menu where it's more userfriendly and far more intuitive to use. We also cleaned up the daily spin menu where the icons are much larger as well as the ability to buy extra spins. So, I just gave myself all the skins as well as the
Speaker A
auras and the kill sound effects, boost sound effects. And I'm going to choose the mecha snake here. Then I'll equip the fa kill sound effect. And then I'll equip one of the auras here so I can demonstrate what the auras actually look
Speaker A
like. And the next part of the tutorial actually shows you how to eat the food and grow your snake. And then also shows you how to boost, which you can just hear the kill sound effect that played right there when I
Speaker A
killed another snake, as well as the aura that appears around your snake when you hit boost. Also, the username on top of the snake shows how many rebirths that they had. And this one's a really big snake. And you can see all the boost
Speaker A
auras are working. But yeah, everything's working as it should. The game is basically fully playable and we can actually put it out for advertising now. Also, while we were developing the game, we actually had to adhere to these
Speaker A
new policies that Roblox had set up where some countries aren't allowed to actually open loot boxes, etc., like hatching an egg for a pet or opening a chest for loot. [music] And it says here, countries like United Kingdom,
Speaker A
Australia Belgium Netherlands and Brazil all banned the ability to uh pay Robux for random items. And you also have to disclose all the odds and percentages [music] of the items you can roll for. And so I asked Codex what
Speaker A
changes we needed to make so that we are actually following the policy and it made all the necessary changes for us here. So this is what the game's homepage is going to look like. It's going to be called Grow the Longest
Speaker A
Snake. And this is going to be our icon. We also have two thumbnails going. We have the main one and then this one. And all we have left to do is start running ads to see if this game could become
Speaker A
successful. So for the experience, we're going to choose our game, Grow the Longest Snake. And for the goal, we're actually going to click plays here because I heard that engagement doesn't actually do very well. And then for the
Speaker A
audience, we're going to do all players. For our daily budget, we're actually going to do $20 a day, and it's actually 11:30 p.m. right now, and the campaign's going to start at 12:00 a.m., which is in 30 minutes. We're going to run this
Speaker A
for custom duration for 4 days. And now we're going to hit publish. And there we go. Our advertisement is published, and all that we have left to do is see if players actually join. So, it's 5:00 in the morning, and we woke up to 16
Speaker A
players in game right now. So, we're actually going to check the game out and see how the players are doing. [music] Oh my god, there's actually players playing the game right now. And someone else just joined. Oh, I think they're
Speaker A
actually following the tutorial. Oh, and they're hatching the egg. Wait, this is sick. Let's see if she spins the wheel.
Speaker A
And oh, she's just going to go straight into playing the game. Okay, these people are actually playing the game as intended. This is awesome to watch. So, I've been watching these guys for a while, and look at how big they've
Speaker A
gotten. This person gaming just encircled JHNN, which was the first in the leaderboard. Oh my god, he might be cooked. Wait, he might be cooked. Yo, [laughter] he actually got him. Oh my god. What?
Speaker A
I've been watching this guy for like 20 minutes and he's still playing. He's just dominating the entire game. That is crazy. We have another person getting onboarded.
Speaker A
Oh, she's just going to go straight in. I'm just enjoying watching these players play, seeing where they actually quit.
Speaker A
And I was also trying the game on my phone earlier, and it was actually kind of hard to play on the phone. And I'm assuming a lot of the players are mobile players. So, I need to actually fix that
Speaker A
if I want the mobile players to [music] continue playing the game. So, we haven't even reached a full day yet of advertising. We've only spent $13 out of $20 a day. And we got 157,000 impressions. [music] The CTR is pretty average. It's only
Speaker A
2.45%. Out of the 156,000 impressions, we got 3,852 clicks. And our best performing thumbnail is actually this giant snake [music] monster one where this is actually a very familiar character. So, I'm not surprised that this one did better. And the grand total
Speaker A
Robux we made in one day is 80 Robux minus this one cuz my friend bought that one and minus one of these because I bought one [music] of them just to test out the gifting system. Other than that,
Speaker A
I think it was a success in my eyes. Obviously, things need to be worked on [music] which I'll continue working on the game after I finish editing and uploading the video. And the link to the game will be in the description as well
Speaker A
where you guys can continue checking out my future bug fixes and updates. But yeah, let me know in the comments down below if you want to see more videos like this using AI to create Roblox games. And make sure to join the AI pill
