Nice! The skullmurai fight can be a bit hard since he has a variety of attacks. Great job on beating it.
I actually didn't think about that particular problem since I didn't have plans to implement leveling in the jam build. It feels nice to solve a problem without knowing it lol. But you're right. I always ended up trying to balance XP between the party in disgaea so that the game didn't become too easy.
P.S: Yup I love stupid puns like that. My username also happens to be a pun in my native language.
