Bones: Graveyard Roll is a 2D action platformer about a reanimated skull that rolls and jumps through a moonlit underworld. You start as just a head. You build your body from the bones of the skeletal animals you defeat. Every bone is a skill. A leg lets you walk and jump higher. A jaw bites. A spine carries more bones and cracks like a whip. A wing gives you an extra jump in mid-air. A tusk charges through shells. A shell makes you untouchable but helpless. Stack more of the same bone and its skill grows stronger. But your body is also your health: every hit tears a bone off you, and it shatters where it falls. You can also throw a bone as a weapon, and you won't get it back. Explore generated levels across the catacombs, the cemetery, the cathedral, the sewers and the drowned depths. Find the key, reach the door, and face bosses such as a vampire lord, a giant scorpion and the Drowned God. Along the way, heal at shrines, spend bones for power-ups, uncover secret walls, and swear risky pacts at altars. Three difficulty modes (Safe, Normie and Insane) add tougher tiers of enemies and cursed foes.
