I found the characters a bit hard to control. I was unable to solve the puzzle because I got frustrated trying to jump onto a platform. I had to wait every time for it to reach the top and return. The guy in the spacesuit controlled a bit too well causing me to miss switches over and over as I would overshoot it. Made me feel cheated by the game a bit. Awesome concept though. if the controls are not as frustrating as it is now I may be able to complete a level.
