best concept so far

Can't run and jump at the same time, but otherwise, looks neat.

Nice music, and descent graphics, but very sluggish controls, moving right seemed to cancel jump, and for some platforms timing it was too hard (for me).

Mechanic is quite simple - you get one key swapped from time to time, so indeed you loose control (from time to time). However I had more problems with jumps that wrong keys :|

Neat concept. My only criticism is that sometimes the jump doesnt give you anywhere near the height you'd expect, and u just miss. Apart from that good job.
