Use the arrow keys to move the cube, click the skip button to skip a level. You can wall jump. Tap around on mobile. Tip: tap to the right to go right, tap to the left to go left, and tap to the above of the cube to jump. Hold to walljump. Full screen not recommended. 100% possible! (Even on mobile!) There are 10 levels. Enjoy!
