I didn't have any time to work on music or sound effects before the deadline, but I do intend to finish the game before November. I did also get some feedback before about adding more frames to the stirring animation and I will absolutely do that. I was worried extra polish would take away from the limited Game Boy feel (and also I was short on time), but it seems like something people really want.
If you're interested in seeing the final game, I recommend following and checking in sometime before November! :D
