Well done for getting the game done! As the person below said, the game felt a little floaty and hard to control, but that kind of fits with the theme! Very hard too! Did you actually manage to finish it yourself?

Interesting concept, but it needed to be taken a step further before it really felt satisfying. As it stands, you only really need to use forward and jump and can just wait for your time to expire to see what the next control scheme is.

There are a number of ways this could be fixed, such as not allowing the player to mouse-look, see how long they have before their scheme changes, and maybe even locking the control changes to the puzzles themselves.

Additionally, the jumping itself lacks feedback and depth perception, which meant that it was incredibly likely that a jump could be missed because of the floaty feeling, not the control scheme change, which I believe was probably the goal.
