Hah, I wondered if that might have something to do with it. My reasoning was similiar in my game Haroldry- the protagonist has a fever at the beginning, so I thought it would be cool to use the Time Fantasy Japan tileset to make the world look feverish, much like your idea for another dimension. That did not alas save me from comments about the clash :)
Sure thing, thanks for making a game and music. Good luck in the Jam!
