Didn't this come out in the 90s?
I have a vague recollection of playing Star Wars Yoda Desktop Dungeons and Indiana Jones Desktop Dungeons that were like bite-sized dungeon crawlers.
bebs,it's a puzzlegame that plays like a roguelike... the monster don't move so you either die by mistakenly attacking a monster or by simplying running out of resource which are uncovered space around (each time you discover a new space you recover some hp/mp) and enemies which give you XP,the thing is that if you kill every monster in the dungeon you usualy don't have enough level's to kill the boss so you have to employ trick,spells and the skill of your class to kill monster that are stronger than you which in return give you more XP
this was the freeware game which is pretty fucking old (4 years? maybe even 5) this new version has all new improved graphics,reworked skills,reworked divinities (they were a system that gave you bonus for taking particular action so for example the melee divinity would reward you for punching stuff in the face and punish for casting magic) and an RPG mode where your progress between level carries each other (where in the freeware each game was contained in itself)
you can try the freeware version here
