Draw Me a River: Doodle a creature, pass the level

Hey Product Hunt! I wanted a game where your drawing is the character, and it has to figure out how to move on its own. How it works: - Draw in the box. Closed shapes become hollow bodies, circles under a body become wheels, lines reaching down become legs with knees. - An evolution strategy trains a gait for your exact drawing in a few seconds, in Web Workers, right in your browser. No server, no sign-up. - Then it's real physics (Box2D): hollow shapes pop on spikes, heavy things sink, top-heavy things tip over. If one part pops, whatever is left keeps going. The twist: every level is a puzzle, and no single drawing passes all 11. Wheels fly over ponds but pop in Axe Alley; a long, low stick creature crawls under the spikes but can't ride a lift. Every failure tells you something. Also in there: a level designer (share your level as a link), a ghost of your last run, and run links so friends can race your drawing. Built with three.js and planck.js. I'd love to see what you draw, and which level beats you :)
