Well, I made a simple music track (did I mention it’s a bit off-tempo?) and put together a short how-to (which probably isn’t enough. I wanted to do a visual one, but I just wasn’t awake enough).
Knowing how annoying spacey music might sound to some, I also added a way to turn off the music, appropriately mapped to the M key.
I also scaled difficulty down by quite a bit. After playing my own game, I was getting massacred almost instantly. >.>

I’ll be glad to change anything based on suggestions while I still have time.
EDIT: Oh, the source is packaged in with it. 😛
