Into the Restless Ruins is a roguelike deckbuilder. Use your deck of cards, representing rooms and corridors, to grow the labyrinth of the ruins. Then auto-battle your way through them, harvesting as much Glimour as you can from the cursed residents before darkness overcomes your torch. Earn favours from the Harvest Maiden, find Relics to trade with the Hen Wife, Wulver and other characters from Scottish folk lore to upgrade and curate your deck, and hope you are strong enough to face The Warden when you can finally reach it.
