Wow! The pixel art is gorgeous! The music is great too!
I think the opening cinematic moves a bit too quickly if the player isn't paying close attention, although this is a bit of a nit-pick. It also took me a bit to figure out what the jump button was on keyboard.
The idea is really cool and original, and definitely fits the theme. Obviously this game was a bit short, but it was well designed and I'm looking forward to what you do with this in the future!
