Nice game, I think I am odd one out with controls, Most of the game including yours is designed with wasd keys (as I think it is more popular than arrows). For me I have rarely played any games with wasd keys so I am little bit uncomfortable as I have to play with my left hand (however I think I would have to get used to with it xD).a Anyway even after that I enjoyed it a lot.
I noticed one bug where when you die on the water at start of level, you spawn outside the platforming area and keep falling and don't die lol
Also I wished that dialog doesn't appear every time I flew upwards as it was obstructing where I was going and it became more annoying than funny
Otherwise great game and unique concept.
