It's pretty much finished, though there might be some changes after playtesting.
As for music, nothing is really set in stone, but I have been trying stuff for some time now. It sure as hell will not be that annoying bleep bloop bleep music I presented when the level was in the experimental stage.
The main thing I am focusing on at the moment is optimizing. And more optimizing. Some optimizing as well. Did I mention optimizing? I shall optimize.
Because none of you are thrilled to play this at 18fps. But fret not, I know what the problem is. It's just really tricky to fix.
