read the ingame how to play.

sound's sadly only work in webkit based browsers as of right now. (chrome, chromium, iron etc.)

you might want to play in full screen to get the full experience (press f11).

this game has gamepad support and against the ingame how to, you can also use the up binding on the keyboard to rotate. (w, ↑, 5 on numpad)
