Great game so far! The only weirdness I've noticed is that I feel like the sound setting change things a bit too drastically. I turned the sound effects down half a line and the music up half a line, and I could barely hear the sound effects.
Also, how do you unlock the beastiaries? I've got two boss CDs and several enemies with the net, but I can't look at them because the beastiary options are grayed out. Do I need to beat the game first?
