Wow! I didn't expect that at all. Really nice idea you had here. I found it a bit difficult to actually figure out what was going on with the future and past thing, I just ended up going for process of elimination, I got there in the end :D. The sound when you move / touch walls were a bit jarring but I really dig the music! Really cool unique idea you have here! I think it could be expanded upon, smoothed out and be a really great puzzle game.
