I found a bug: the buns hairstyle for the slime girl can't be deactivated to return to the defaul hairstyle, so it's necessary to have another hairstyle unlocked as well in order to switch back to default.
Also, I think that the belly bulge is way too prominent compared to the tentacle movement and the oral tentacles reach way too far back in the skull.They should stop a bit before the throat, or at the middle-front of it, not so far back.
