What a awesome and challenging game at the same time!
I absolutely love the idea of this game, that the controls change over time, combined with a great execution, how you display the time left with particular controls, so it won't ruin a jump or the thight controls that feel right at home (especially with the right WASD controls).
Only one thing that bothered me was with the level progression. At first it is easy then it gets harder than harder and then frustrating (the part where you can fall down to the beginning) but towards the end being really easy. But that is only one small thing being toped by all the great things.
Fantastic job!
(P.S.: My game has exactly the same name ;-)
