I liked it, but it didn't keep me playing for long. It seems like it's supposed to be very simplistic, but the addition of music during gameplay would be a nice addition, other than that, it was just kind of gray. It didn't take any chances. I would suggest more of a variety when incresaing difficulty (not just increasing speed) and the addition of music that could be very simplistic in nature (like a chiptune or something) to keep the atmosphere of the game.
