The music is nice and the movement is quite smooth, though I had a bit of trouble getting the wall jump to consistently do what I wanted it to. Same with the backflip, which I very much like the inclusion of but couldn't make happen on purpose. It seems I'm immortal, and I have to jump to go through doors. The star of the show for me here is the freeform level selection system which does a great job of encouraging exploration. Even if there isn't a whole lot of variation from room to room, it psychologically makes me feel as though I'm uncovering something by completing them. Solid entry overall!
