Lately there have been more and more of these dimension/perspective games, like Project1on, but you guys did manage to make it unique. However, the way you've implemented it makes it a bit unintuitive to use. Perhaps you can show partially transparently the other layers. It would also be nice if there was some music in the game (other than main menu).
I got pretty far in the game (I think). Though, I couldn't figure out how to do this level with the moving platform. A couple dimensions back there is a lower platform, but I can't jump and change the dimensions to reach the moving platform.
