I am not too good at making music yet, and the sound effects were added on the last day of submission, so I did the best I could in the left time. I am planning on giving sound design more time from now on.
As for the overworld, I made it to give some environment to the idea. Walking around in the night, entering people's houses and going in their nightmares is supposed to make you feel like you are actually trying to save the night.
Good to know you still liked it!
