Enjoyable
Solid platforming and I thought the tutorial voice over was a cute touch, but once the game got into more precise and timed platforming the constantly changing controls were a constant source of frustration. Too many times I would be mid way through level 18 and on only to be thwarted by trying to jump with the wrong relative key.
As a general rule, Jump should always, ALWAYS be the same key. Especially when the game does present a higher amount of timing or precision in it.
