Kleromancy

What if Slay the Spire used dice instead of cards? Build your own 3D dice, customize their faces, and roll them with real physics in this turn-based roguelike. Create powerful combos, manipulate your rolls, and fight your way through 7 corrupted biomes.
Overview
Kleromancy is a deckbuilding roguelike with a twist: you don't play cards, you play dice.
Every die in your inventory is a probability module with six interchangeable faces—it's your deck, your hand, and your build. In combat, dice drop with real-world physics onto a felt tabletop. Read the top face, manage your energy, and pull off attacks, blocks, heals, and special effects. But the table isn't just for show: puddles, whirlpools, bumps, and collisions will mess with your rolls in real time.
You wake up aboard the Theseus Ark, a generational station built to escape the Great Chill—the cataclysm that turned Earth into a frozen grave. A calm voice, the Nexus, guides you: you are an antivirus. Your job is to purge anomalies, push through corrupted biomes, and take down the Guardians locking down each sector.
Work your way through a branching map filled with multiple routes leading to the final biome. Fight off mini-bosses, collect meta-keys across your runs, and push toward the Scrapyard.
Chase victory by experimenting with hundreds of different faces, collectible dice, passive relics, consumables, and unlockable character variants. Stack and mix tons of status effects like burn, poison, vulnerable, strength, barriers, or parries. Then put your builds to the test against multi-phase bosses with charge-up mechanics and unique attacks.
How far will you make it through the station... and what will you find once you cross the point of no return?
