Instructions are in game. WASD to move. Right arrow to rotate the world clockwise. Left arrow to rotate the world counter-clockwise. Press R to restart the level.
I've been able to beat all the levels up to the you win screen in under 1 min 40 secs. This is a extension of a pen platformer engine I made previously, the rotation is implemented on top of that. There is also a bonus level if you can win the You Win screen. All levels are possible, and there are no glitches required to beat the game. Tell me in a comment if you find a glitch.
