Grimslair

Play a deadly card game with your father, Grim, and fight to bring your girlfriend back from the dead. Battle brutal enemies, collect and level up cards, empower them with powerful modifiers, and rewind time to undo your mistakes in this dark-fantasy roguelite/roguelike deckbuilder.

 

Rip Soulwords from humans, animals, and the undead. Fuse them into your battle cards to change how they work, stack brutal effects, and build wild combos. As your cards level up, your deck becomes stranger, stronger, and deadlier with every loop.

 

 

Most enemy cards have Chain Connectors on both sides. Grim’s five-card deal can create deadly combos, letting him play multiple cards in one turn. Break his chains, crush his enemies, and survive the assault.

Every day is a race against Grim’s Soul Quota. Track enemies through graveyards, forests, caves, deserts, and snowy mountains, then choose which battles are worth the risk before the clock runs out and the loop starts over.

You do not survive Grimslair alone. Your husky fights beside you in exploration and combat, with its own cards, abilities, and ways to grow stronger. Level up your dog, pet your dog, and turn loyal companionship into a deadly advantage.

Meet strange vendors selling powerful cards, upgrades, and deck-changing effects. Buy what you need, or kill them and steal everything they carry. But every choice comes with lasting consequences...

When a run ends, the clock drags you back to the Chamber of Time. New perks, battle cards, enemies, and Soulwords reshape each loop, forcing you to adapt, experiment, and push deeper into Grim’s world.
