Your goal is to reach the black portal. Use the Arrow Keys or WASD to move and jump. In this game, there's no way to lose! If you walk to the edge of the screen or fall, you'll land on the opposite side!

Push boxes to reach higher places. Later levels will contain white platforms with a black line in them. You won't be able to pass through these, but the boxes can! Don't touch the spikes, or you'll have to start over.

Walk through the arrows to flip gravity and your movement controls! Boxes will also be affected by the gravity switch.

If you get stuck, press R to restart the level.
