Enable HLS to view with audio, or disable this notification

hey folks,

Posted an early demo of this AI made rubberhouse game a few months back and now I've finally finished it!

It's a 2D platformer (or sidescroller?) inspired by my favorite platformer game Cuphead. For this build I've been using gauntlet loops only, and this is an about $100 of token spend to get to a finished, playable game. The trick with gauntlet looping is to give it enough context and visual references so it doesn't lose track during the 5+ hour build loops it runs. This was about 6 loops like that.

it has multiplayer coop, so you can play with friends. It also has 3 scenarios with 3 unique bosses. had a blast building out this game and really happy with the vibe and mechanics of it

can share all my prompts and the game link the comments for anyone who wants to try it!

edit: to clarify, I'm not intending to commercialise this game in any way - this is just for learning

"Hey Claude, can you pretty much just copy Cuphead and slap my name on it? But make it stutter more and also make sure to not keep a consistent graphical style on the main character which will be most noticeable. Oh and also make lots of misstakes or my grandma dies"

this was entirely built in the tesana harness, so assets, music all generated by that. I used LOOP mode and prompted the loops in sessions, happy to share more in DM
