This doesn't feel fun as a platformer game, not being in control of my movement takes away what makes these types of games special, especially when most of it is trial and error. Platformer games shouldn't be made like this, period.

Well, under normal circumstances maybe I would agree with you, although I wouldn't formulate it as a hard fact :D
However the theme of this gamejam was "Out of control" and the game discription itself states that "Reaction checks and mindgames are the core components in this concept" - so it is indeed not a typical platformer.
Nontheless sorry you couldn't enjoy it.
