good game, but...
...it sucks that you lose autmatically just because you mess up a single level - I got to level 37 or so, and I just don't have the motivation to try it again, the game isn't *that* good. ;)
Also, (although maybe that comes in the later levels), you didn't make enough use of the potential difficulties of the two figures moving simultaneously, in most levels they are just mirrored.
