This is the most fun I’ve had in ages, and it can be yours for about 8 bucks. Pick one of 6 classes, navigate from room to room Darkest Dungeon style, fight baddies, win new cards, upgrade others or remove them from your deck, find loot, etc.
And just when you think you are unstoppable, get annihilated and start again. Brutally challenging, quick to play, hard to put down.
Each run will earn you fame, which unlocks upgrades and passives that affect starting hit points, change out cards in starter decks for each class, give companion NPCs new abilities and passives, add new cards to loot tables, and more. You also get to keep gear you find and use it on your next character, which also helps to make you more powerful over time.
It’s delightfully fun, even when getting your ass handed to you.
