Generally Ludum Dare tends to produce things that, well, aren't remotely interesting. This is a nice exception! Really solid little arcade-style game. Simple, cute, and above all, unique - I'm not sure I've seen anything quite like this! The sounds are perfectly fine, and I appreciate that you didn't worry about putting music in - the quiet fits better. The controls are responsive and simple, which is something people seem to overlook far too often. This is an extremely solid, well-executed game, that I could easily see being fleshed out into something timeless. Great job!
