Solid platformer, functional art. Everything is said already about music and sound (settings do not work btw, at least for me they didn't). But I cannot express enough how bad this camera movement is. Those slow twitches every time you jump, those back and forth movements, it gave me A LOT of motion sickness really quick. I don't even know, how did you achieved such an effect :D
That being said, it is a solid effort and a pretty fun game (at least part I played before I literally had do turn it off)
