[Unknown] [Unknown] Hard Dungeon-Crawler RPG

Sorry if this is way too vague, but maybe someone can help me out… I watched a video on youtube a couple years ago about this dungeon crawler game (thought it was by Jacob Geller but can’t find it on his page). You could play as a couple different classes, one of which was wizard… the game was really hard, and I think at the time kind of obscure. The point of the game was to get into a castle, I think, and at the beginning, you got ripped apart by dogs. I think you could gather a party of fighters, and the progression was really slow… When you thought the game was almost over, a whole new cycle of stuff would start up and it just kept going… Ugh I know that isn’t a lot to work with but it’s really bugging me that I can’t find the game or the video I’m thinking of.
