Well firstly i have to say that this was a really good idea for a game and secondly i thought the way you went about increasing the difficulty is one of the best ways that i have seen for any game here on newgrounds. You were able to add in the different colors and the different speeds which really did make this game challenging. I thought the different level backgrounds were cool and the background music was very spacey which suited the style. Overall a great game.
