This game should be called "Ledge Jumper." It's the same thing over and over with you gaining high after a certain point. A decent idea but poorly executed be doing the same thing over and over.
Good game. I only get a problem when trying to restart the bonus map. It just goes black and then won't let you do any of the option in the options menu.
It's a lot of fun. I only found 3 of the 5 secrets. Also, after I finished the game, I put a key in the second slot in the machine and then went to the secret room. The keys disappeared in the 2nd slot but not is the 1st slot. I couldn't re-find them where I was looking for them. It might be a bug, but only if you are going back after you have beat the game. 5/5
