I started playing Ring of Pain. It's a deckbuilder-ish roguelite. There isn't really a deck, it's more of a loadout-builder (or tableau builder in boardgame terms). Meteorfall: Krumit's Tale is the closest thing I've played before. RoP is sort of like a 1d version of that. Fun and fairly unique mechanics, smooth implementation. Runs great on the steamdeck too, good controller support.
