This game has a nice idea, but I think it can be a bit unfair at some points. For example, there are multiple situations where you have to fall down into spikes or water without knowing that they were there. Also, there is a bug that let you make a double jump before unlocking it, by pressing W very fast. Anyway, I liked the game, and was fun to play.

Oh and that triple bow is really op :D
