Hey DiedToANero, and welcome to the forum.

Multiple save slots were a blind spot of mine; Demon didn't actually have them until semi-recently (probably because I almost never have multiple games of roguelikes in progress at once myself.) and wasn't originally coded with the idea in mind, but I will try to figure out a way to handle this and put it in the next build.

Thank you for the suggestion, and good luck in the Tower!
