Some bugs I noticed during my playthrough of the demo:
-Laurel is referred to as Elaine occasionally - in the character select room, and I believe also in the first conversation you have with her and Cassidy.
-Asami is referred to as Azumi in the character select room
-You can encounter an already-chosen character in the character select rooms, and accidentally selecting them again means you miss out on a companion for that run. Sometimes characters also show up twice in the same character select room.
-In one of the conversations with Leaf (where she asks how you're enjoying Blackgate and goes over donating to factions), after you finish talking to her, her portrait does not disappear from the screen until you go talk to someone else
-In Helga's conversation after a couple of clears (the one where she asks about your opinion of the monsters in the dungeon), when selecting any the second set of options (why did you come here/thoughts on the dungeon/you are a helpful cleric/let's adventure soon) it will end the conversation instead of looping back to those selections like it does for the other characters.
-In one of the conversations with Titania (where she says "you have my strength whenever you need it), her portrait does not disappear from the screen until you go talk to someone else
-I think I saw Blair learning a skill called Lullaby at level 2, but I don't see it on her skills screen and it's not available in battle
-The level up notification said Titania learned Quicken Movement at level 4, but that is not in her skills
-Minor typos scattered throughout the text
-The open door texture for Minerva's home is glitched, it's half as wide as it should be
-Is the Julia scene at the hot spring supposed to be a black screen?
-None of the chests I've come across have had anything in them, aside from one with a placeholder mimic message
