About Grimslair
Grimslair is a dark fantasy roguelite deckbuilder where every run is a race against Grim’s soul quota. Build brutal card combos, rip Soulwords from the living and the dead, break Grim’s deadly chain attacks, and rewind time when your run collapses.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. Use blank Tabula Rasa cards to create custom battle cards that are uniquely yours.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, interrupt his assault, and survive long enough to strike back.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, using 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 leaves a lasting consequence...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.Every card, character, and piece of game art was hand-painted by the solo developer over nearly 6 years.

Hello My name is Lincoln I am autistic I have vision problems I need my glasses to help me to see having my laptop close to my face helps me to see the game better. I grew up with yugioh the anime and wizard the Canadian card game I play cards with my family from time to time. i am also a card collector of Doctor Who and Star Trek. This game called Grimslayer takes time and patients to learn you build your deck up from the start but if you die you have to start all over with a new deck the decisions you make will impact your journey though the game. Its a quest to save your girlfriend from the grim reaper to bring her back from the dead with new addons on the horizon for the game its only going to get exciting for card players Final Verdict for grimslayer is a 9/10 by Lincoln Williams show reviews10 found this helpful
I would absolutely recommend this game! Not only is it a battle card game, there is exploration, battling the elements, perks, classes etc... RPG card game, love it! The art style of the game is fantastic. The dev (AUSTIN) has worked very hard to bring this game alive from a passion project to a full scale game. Please give it a try. Like someone said, you will die and then come back for more over and over and over! :) Can't say i have been this hooked on a game since slay. TRY THIS GAME!6 found this helpful

Enjoying the game. Not a card game player; however, this game seems interesting. Will keep trying. I'm dying a lot but I like the improvements I can make even if I die so that it is not just a cycle of dying.2 found this helpful
This really is a wonderful roguelite/roguelike hybrid. It features a creative card upgrade system that you can easily lose yourself in. It's nice that progression in the dungeon breaks away from the traditional points on a map, a la Slay the Spire, and the dungeon crawling aspect as well done. The combat system is definitely the highlight of the game, with its unique "Chain Break" mechanic being the standout feature. You can't just endlessly spam your deck to loop for infinite damage, and having to take into consideration how to link your cards together to break your enemy's combo is a really important part of succeeding. You also have to think about leveling your cards up and auto-attacking oftentimes results in failure in the late game, when you don't have your cards scaled to enemy health and damage. The reason I say that this game is a roguelike/roguelite hybrid is because you choose if you want to do a meta-progression system in a Roguelite mode or a hardcore Roguelike experience where you only keep upgrades in each dedicated run when you create your save file. I haven't jumped into the Roguelite system yet, but have thoroughly enjoyed the Roguelike mode a bunch. The …1 found this helpful
