I think this is a fantastic idea with a lot of potential to be turned into something really original. The idea of playing with our notions of up and down / left / right and scale as you move "left" and "right" along a spiral that unwinds can has many possibilities for dynamic puzzles, movement and lateral thinking.
The current implementation is a little sparse on action (I most of the time I just moved "right" and didnt need to do anything else - but this was a one week project built around an original idea/mechanics so it couldn't really borrow ideas from existing games to get a quick start. The polish will come with further development - especially if a final product could match the style of the header image - it would be a very beautiful game.
