The Devil's Due: you already lost your soul, so cheat your way out

The Devil's Due is a poker roguelike where you fight one-on-one poker battles against demonic foes, with hand strength as damage and the sum of your cards as defense. Both sides draw from the same deck, so every card you add, remove, or tweak can help your opponent too, and each cheat raises their suspicion meter. You unlock an expanding set of cheat tricks, relics, and paths through Hell as you try to fight your way back to freedom. Windows only.

The cheating can add a lot of depth to both the battles and the deckbuilding, and runs can feel like they ask for a new approach each time. Some damage and enemy details may not be immediately clear. It's still a small, early audience, so take this as a tentative recommendation.
