A fun little game using the control changing idea in a way that isn't too fustrating. Levels were short and the fact that the 4 same inputs were swapped made adjusting to the new control scheme easy and quick.
Even with the countdown, it still felt a little jarring to suddenly do a move you weren't anticipating, definitely when you're already in the air, this causes slowdown as you generally just wait out the countdown between every few jumps, rather than risking everything for little reward. The last level with the wall of spikes addressed this, as it applied pressure to the player, more stuff like that!
Good work however! A fun little game! ^-^
