Runs entirely in the browser: no install, no sign-up, on any phone. This game is heading for Google Play — the demo version is open here on the playground.
Steve is a five-part construction kit: you throw both arms (and stack them into a TOWER to reach a high button, or a BRIDGE across a gap), take your head off and send your legs on ahead — every part acts on its own and you switch between them at the bottom. Pressure plates respond to WEIGHT, and an arm on spikes makes a fine doormat. Ten crypts, and you only get out IN ONE PIECE. English by default, Russian in the language switcher.
Open the game and start right away — no install, no account. On a computer use the mouse or arrow keys, on a phone just tap. Your result is stored on your own device.
