Never played something like this before.
It's original, as far as I know I have never come across another game like this before. It was fun, a nice, fresh, original idea, which was very challenging (especially from about 14 onwards).
Took me a while to get used to the controls, and to be perfectly honest, I never really did, but I managed to get a good grasp of the way it works. Rest assured, I managed to complete it eventually (definitely without cheating).
The only thing I'd suggest you could do is maybe enhance the game graphically, the spike traps looked really bland, and not too exciting. The game itself worked very well though, no problems, as far as I could see.
Good job. That's two good games from you in one day. :)
