Wow! Great idea and nicely done. Very good job. This was much fun :) The core idea gets repetitive, you quickly forget the aspect of "not real" and the turning of the cube becomes "just an mechanic". Still, i could see this concept expanded into affecting other elements, too, so the changing of an important element becomes a suprise more often, which you have adept to then. Very cool! Only the controls are difficult and unituitive, because your perspective makes it not clear, what going up, down, left or right would really mean.
