Nice concept.
The graphics were not bad, the idea of the game was brilliant but could of been a little more challenging and I'm not sure if there is any (If there is, I didn't get that far), but the game could of used some checkpoints every 5 levels, maybe.
Also, if you added music and sound effects, this flash would have a much higher score, although I think it's quite underrated, already. Use sounds next time and your talent will be seen more often.
Lovely game. I really enjoyed playing this. Pretty addicting too! 10/10.
