Hi,
Great job on the music. Who gets annoyed by chiptunes? If you worry that players are going to be bothered by the music, 1) Reconsider the music you have in the game because you obviously don't think it's ambient enough and 2) Add volume controls.
I'm glad you're trying to do more with less when it comes to the level design.
It's a lot of work and the logic can get kind of funky, but you really need to work on more fluid controls. The buttons aren't a problem, but user input in games should typically "flow" smoothly. This demo feels like it was "coded" in Stencyl...
Overall, really interesting. It has heart but lacks polish.
