Gah, I'm sorry, but the music you chose is absolutely horrible. The one in the barren town is exceptionally grating. Also, the underground area could use some spicing up, cuz right now all it is is a ridiculously long and boring hallway. And it could use some better music.
Also, shouldn't the first boss kind of show up out of nowhere? I mean, he looks like a freaky ghost, so it would work.
