So far it's a great game, but MAN you have to tone down the difficulty on the slime queen by a ton. You're way too handicapped. Maybe make the vore attack hit more often or heal you by a little each turn, I dunno.
Phew, that's a bit of a relief.
No clue why you didn't level up, since you're supposed to gain enough xp to level up instantly, but I'm glad you did now so you could beat the boss!
Also, don't worry about it coming off as rude. Some other people have encountered the same problem and trust me, there has been ruder lol
