About:

A hundred physics puzzles across ten worlds, each a Rube Goldberg cartoon with one part missing. Seven crayons behave differently - blue stays put, orange is heavy, green bounces, yellow floats, purple swings, red boosts, black is a magnet - and every world ends in a boss. Use as little crayon as you can for three stars; the live 'Quick Draw' levels start on their own and make you draw against the clock. Physics by planck.js, audio synthesised in WebAudio.
