So many glitches. I'm constantly finding places where I just walk through the walls or floor. The worst ones are like the one on level 3 where if you just keep continuing to the right, you'll walk through the wall and then fall forever on a screen with a black background.
A decent game bug the light-tapping type of jumps, make this a "do you have patience" game, rather than a sit back and have fun game. ='(
