Well, this edit is supposed to be sort of silly. I'm trying to to make it utterly ridiculous, just vary contrasted. Point being, it wouldn't be creepy music. I need something very simple, not something so ironically cheerful that you stop playing instantly. The game will still be creepy, as I can't figure a way to change the darkness fog and such.
Basically, I need a very simple, maybe a little cheerful song to play in the background. Nothing very present... Nothing too creepy or happy... But not tense, not very at least. I'd still have to switch out the other audio. But at least the GFX changing is done for now.
