Wow, very very impressive game. I have no idea how you managed to make so much art and put together so many levels in so little time. So congrats for that!
The game also looks amazing and is very well thought out. The only thing that I would actually change is the initial tutorial video. Instead of playing that long video before starting to play I would split the video in smaller chunks and only play the chunk that is relevant to the next stage. Otherwise it is a little bit overwhelming.
Anyways, this is only a minor detail, great great stuff!
