Ahhhh...
I think that this had the potential to be a good game, but fell a bit short on the execution.
The controls are about as simple as they get, and yet they're so unresponsive that it becomes frustrating. The framerate fluctuated too much as well, which should not be happening on any computer with a game this simple. I didn't really like the music, but I'm not going to dock you any points because of that, since different people have different tastes. The sound effects were minimal, however, as were the animations.
I think this game needed another week in development before you released it. It has potential.
