Not sure if it's already been mentioned, but the gothic lolita outfit seems to be bugged. When I equip it, it looks like I'm not wearing anything besides underwear.
Ah, some of the sprites were missing for some of the outfits, so it would just show the player in their underwear. Version 0.31 was just released, and if you download the latest patch for it the game will have sprites for most of the clothes now.
