I vibe coded this Roblox game using only Claude.

I vibe coded this Roblox game using only Claude. So someone asked me what Claude model do I use for my Roblox development and do I have any specific tips? For me personally, even though I have access to Opus 4.6 and 4.7 on Claude, you can downgrade to Opus 4.5 and it's what I do to get more usage out of my prompts. Because when you're making a game like this, it's not something that can be one-shotted and AI can do perfectly the first time. Even though Claude scripted the game, even though I was on the normal Pro plan, it was still a constant debugging, planning, prompting, and reprompting until everything worked the way I wanted it to. The biggest thing I would say is don't think of it like AI makes the whole game for me, but AI helps you build something one at a time and you direct it. Because you might prompt for one mechanic and then you need to test it, then reprompt it to make sure that's how you want it to be and say this didn't work, that didn't work, I want it to do this instead. In your prompts, you should say exactly what you want the system to do, where it should go, how the player interacts with it, and what kind of structure you want. For example, here's one of my prompts that I use for one of my games. The second biggest tip I can give is do not try to one-shot the whole game. That's probably where a lot of people mess up the most. If you ask it for a whole game at once, the code gets really messy fast, the systems don't connect well, and when something breaks, you don't even know where it messed up. It's way better to go piece by piece. For example, do one system at a time, whether it's currency, UI, shop systems, whatever your game needs. Build one, test it, fix it until it's done. Sometimes the logic works, sometimes the code works, but it feels bad in-game. And sometimes you want the code structured differently for future features. And that's why prompting matters so much. The better you are at describing what's wrong and what you want changed, then the better results you're going to get. I hope this was helpful. If it was, leave a follow. I don't know if I should do more content like this, but I'm happy to tell you guys more about my experience.
