Your goal is to get the cube into the portal. There is a catch: you can't control the cube! You CAN control the level, however. Rotate the level using A/D or the Left / Right Arrow Keys to rotate the world and watch the cube roll.

But be careful: some levels contain hazards like spikes that will destroy the cube! As you progress further and levels get trickier, rotating at the perfect time will be key.

Press R to restart the level if you're stuck. Press L to return to the level select screen.
