Interesting game. At first I thought it was an endless runner but they have different levels. I liked this more than I expected. I could see myself playing this as like an iPhone game. Could use a bit of an introduction to the various concepts - green cubes being okay, or hitting walls that are the same color as the floor also okay, for example. Surprise shop was a neat touch, and removed my prior criticism of not having a reason for the points. I also liked how it used physics - how your cube spun going off ramps and that would change your orientation. Neat. Negatives - no way to quit game that I could find, had to alt-tab and terminate program.
