Caves of Qud is phenomenal and you won’t regret playing it. If you have a phone, I’d highly recommend Shattered Pixel Dungeon. It may be one of the cleanest versions of the genre. It’s also available on PC, but I’ve never played it there.
Similarly, I think Hoplite on the phone may be the most distilled version of the genre, pared down to the barest essentials and utterly glorious as a result.
Do you have a strategy for frugal salmon? In my neck of the woods, it’s a rather pricy protein.
