Well it seems my attempts to get full-screen mode working completely last night for the release resulted in messing up windowed-mode some. I never even realized it, so thanks to Alicia for mentioning it. When you switch away, then switch back, it doesn't start the music again. I also noticed there's a redraw problem. Not a big deal to fix, I just haven't gotten around to it yet, so I'll do that before I release v1.01.
I've also been told by a couple people that the music track I included isn't that great, so I may replace it for the demo. I thought it was pretty good! Despite being repetitive. But that was due to file size. I'll stick a longer/better one in there in the next version or so.
I'll also add some sort of button or visual indication to the game that F1 is help.
