This was a really amazing demo that had a similar style to about-face. This game was slow to start, but rapidly grew into a phenomenal puzzle-platformer. The idea of incorporating different dimensions was ingenious and add a significant element to the puzzles in each level. The only problems I had with this prototype was the repetitive background music and the fact that you had to click each time to start a new level.
Other than that, this was a very enjoyable game.
