Love it
My only suggestion is to make it full-screen... or perhaps down-loadable, however if you allow for download sell it for like a dollar I'd pay a dollar to have it on my compy. It's a fantastic game that's fantastically simple. I would like to see instead of perhaps keys for director of bullets mouse direction? Granted It's find the way it is, it would be interesting to play with a mouse and WASD setup.
