Pretty neat! I would say that how the level layout is setup, it doesn't really guide you through the room in a neat flow that's important in these kinds of 3d platformers. Ideally the player always knows where they're going and can just figure out how on the fly. I would also like a bit more snappy feeling movement controls, it's currently a bit floaty.
Also would be nice if there was a restart button or the water killed you fast.
The amount of different elements for use in movement is quite nice and makes the levels more interesting.
