As others said the collision hitboxes are a bit frustrating. For a precision platform this lacks a variable jump height and coyote time to feel good. Art is nice and simple. Audio is just a single sound when you jump.
Also I got stuck on this level because the game doesnt explain how to open doors? In one of the first levels you also could get to the door but to go through it I had to jump from a higher position but I do not know how I am supposed to do it here.
