interesting experience. I do have some feedback though:
- I didn't feel like it really fit the theme, you could have made it one long level instead of three separate ones. Although then the question would still be: what does the loop add to your game that it otherwise wouldn't have? How does the loop define your game and make it special?
- It would be nice to have a button that speeds up the process, because when you die, it can take a looong time to get back to where you were.
Other than that pretty good! :)
