A birthday adventure game made as a gift
Claude Code built an HD-2D polar bear adventure with eight minigames and boss fights in raw WebGL2, with art generated in code.
The full story
Instead of a card, the maker built a friend a birthday game with Claude Code. She plays a polar bear travelling through eight cities to recover eight "little eyes", with a different minigame in each, then an evil broccoli steals them and she must win eight boss fights before a surprise party.
It was built with raw WebGL2 and no engine, and even the art is generated in code.
