The pain threshold for next level(s?) is too high, even with borderline bug abuse it likely takes more than one try, which is a bit much. Furthermore, the colliders don't seem awfully accurate, which just doesn't feel very fair. Speaking of fair: The random nature of things makes it so that there's a high chance for scenarios that you can't possibly win, that also doesn't feel great.
Then again, if your goal is to create pain, I suppose you achieved that!
