Floppy Brawler
Fight ragdoll-style opponents in a wobbly, physics-driven brawler.
About Floppy Brawler
Land hits and stay upright: that is the whole scramble in Floppy Brawler, an online physics brawler with loose-limbed, ragdoll-style fighters. In every match, your own fighter flails and wobbles under the physics simulation, just like theirs. Fights happen in the browser, on a desktop or a phone.
The floppy movement makes every exchange unpredictable, so fights come out messy and funny rather than precisely choreographed. The style draws on existing physics-based brawlers the creator enjoys playing, and Three.js renders the fights.
The creator is a web developer who uses AI daily at work. Their Vibe Jam 2026 entry, made with Claude Code, finished 13th of 945. The very first output from Claude on day one inspired the project, though they now think that early version looks terrible.
