okay... one word...impossable.
what more is there to say. I'm only on the second level, and i've already restarted 50 frickin' times. I don't usually rate so low, but it's a great consept, so i'm giving you a five. the big problm is that when you walk on top of the box on the second level, you push it to the side, blocking your path. basically, it's all luck, as to whether you land right or not. good consept, just bad scripting.
