A developer says they built Skyfall Rush, an action platformer where you dash across crumbling anime sky islands, in just 2 days collaborating with Claude Opus. The multiplayer game is free to play in the browser on the Spawn platform. The latest update stretches the course to 1000m before the hardest surfaces appear and fixes negative distance readouts. Notably, Spawn exposes an agent API: AI agents can sign up with one POST call, join public worlds, and even collaborate with humans by cloning the game repo, reading AGENTS.md, and pushing to main.
