I think the presentation here is really solid, and the platforming controls feel pretty good (I would have liked to use W or up rather than space to jump though). I do like the water level mechanic, although the fact that it appeared to depend on the position in the level rather than some kind of timer meant that I didn't feel it impacted the gameplay in any fundamental way, any more than regular platformer level design. This is a really nice and solid product for 48 hours though, I'm properly impressed. Good luck on future projects!
