Incredible demo. Adorable characters, fun game play. I'm guessing only the first three areas are open because after beating the necromancer nothing else opened up. Some things I would suggest:
-Remove retreat button on the last screen of a dungeon. I thought continuing after beating a boss would make me keep going further but it turns out it just "completes" the dungeon.
-The game seemed to be depend on VSync to run properly. I'm not a programmer or anything so idk how this gets fixed but I usually have Vsync off and with your game, having it off causes it to run at max possible processing speed. (this means all actions, animations, etc happening in milliseconds)
-A better way to understand what gifts characters would like? Was kinda guessing off personality which was easy for our goblin and ... werecat? But it figuring out what our necromancer liked was painful.
-It seems like blind is a permanent debuff? It never seems to go away once applied in a fight.
I've never played dnd or any ttrpgs so idk how it all works or if this is normal, I can't quite give really good advice since I'm not versed on the dnd rulebook stuff.
