Stuck on 12 as well. It's fun and the idea is great, but there are too many little things bugging me. That's just a matter of personal taste, though, so I won't return because of it but I won't let it affect my rating.
Fun game. I'm currently stuck on level 12.
How do you get the keycard on level 2?
Awesome game! Level 30 was really a hell! The cheat is that you need to make your reverse clone jump when you're already in the air after jumping over the drill. When you land in the button, the ray is deactivated and your reverse clone is safe.
This game feels like it was made with gamemaker or something. Regardless, it's an unique game, and the splitting concept makes it even more interesting. Although the animations could be a little bit more crisp.
