My highlight in your game was the whole intro sequence. Starting from introducing a nice background story, seamlessly leading into a tutorial with meaningful obstacles and finally into the actual game play. This is all smooth as butter - really well done! The controls also feel just right. The only bigger issue I would mention are these "jumps into the unknown". This is of cause my personal view (not playing too many platformers), but I have more fun when I can execue something by measure+skill rather than by quick reactions (says the guy who made the flappy bird clone with little light :-D).
