Nice concept, even if I find the relationship with the theme a bit far-fetched ^^.
I love the setup, and the fact that you had time for a intro cutscene is amazing (but I must admit that I would have loved to retry without seeing it ^^') ! The circular effect of the world is also a neat idea, and really adds to the quality of your game!
The game itself is a bit simple, the movement felt a bit slow, but overall, it's still a nice little entry. Good job =)
