I don't mind a game that expects no mistakes from the player, but I think it's reasonable to have the same expectation of the game. I've thought hard about whether to post this review, but after the balloon glitched *through* me on the drop section, I feel like it's fair criticism. On another run, I jumped directly through the balloon twice, and hit it twice on the same contact once. It's perfectly fine to make a challenging game, but the functionality of the core mechanic should be on par with what's expected of the player.
