The art is beautiful and the background music fits very well. The idea behind the controls is interesting but I think it would shine more if you had designed the level around the controls more (some puzzles that force you to switch, maybe navigating some enemies). Also, I personally found the story told through the narration a little too cliched and the fact that there was narration took me out of the game a little. Maybe just sticking to the visual storytelling which you do very well would have been the better option.
