Not bad
The controls weren't that hard to get used to, but waiting for the robot to charge his jump takes too long, in my opinion.
The hardest part is killing the guards. There's no way to kill most of them without taking some damage and there doesn't appear to be a way to regain health except passing a level. If you try to get behind a gaurd and claw him you miss.
I would a different way to approach the guard issue if you want this game to be really good. Also, you should make the 'puzzle' aspect more challenging.
