It's neat, but there's some things you could improve. The hitboxes felt janky. It's better just to use a box, rather than the actual shape of the character. There seemed to be some kind of wall jump that I'm not sure was intentional, and jumping seemed to be weird in general. I'd make it so either you jump on key down or if you hit the ground just after, or you jump whenever you hit the ground and have jump held down. I'd also make it so you don't move while the level rotates, and the rotations happen faster. And either you have to be on the ground during rotation, or it's limited to one rotation until you hit the ground and have things that require it. Music and sound effects would be really nice. And it would be good to have some kind of end screen and probably instructions at the beginning.
