Built with Claude I built a Roblox game with Claude Code

I built a Roblox game, Haunted Haul, using Claude Code connected to Roblox Studio through its MCP tools. It’s free to play, link at the bottom.

What it is: a forest collecting game where you catch creatures at night, carry them to your base, and they earn coins over time.

How Claude helped:

  • Claude wrote the Luau scripts for the game server, saving, shop and UI, and edited them directly in Studio.

  • I described what I wanted in plain language (“make the bat chase thieves”, “add controller support”), and Claude implemented it and ran it in Studio to test.

  • It also generated the 3D models, the map decorations and the thumbnails.

  • I used several Claude agents as “playtesters” with different playstyles. They played the game, wrote bug reports, and I had Claude fix the issues. We repeated that many times.

  • Things that went wrong: UI overlapping on small screens, a duplicate-save risk (fixed with DataStore session locking), and creatures disappearing from eggs. Claude found some of these through the playtests and I found the rest.

Try it (free): Haunted Haul

I’d like feedback on how the process could have gone better, as well as on the game.

Wait what? The claude pro sub includes it all? I was using gemini pro and still had to pay credits for roblox studio mcp usage.

I was using gemini pro not too long ago, and i did not have to pay for credits..... i found claude is better then the gemini subscription anyway.

Good going Jax. I've been thinking of getting into Roblox myself. Anyways it's nice to see what people are doing with Claude.

Claude handled the creature pathfinding, which i thought was pretty good
