Bearskull

Bearskull is about reaching Sorkin, an evil pumpkin wizard, and defeating him and his undead followers. No living being has succeeded so far. To get to Sorkin, you must fight through the Land of the Dead and its different levels, then roam the Overworld while trying to leave the undead behind.

Fight and grow stronger

The undead learn and become stronger as you progress. Collect their souls and spend them in the shop to upgrade your equipment, including your sword and backpack, so you can keep up in the fight against Sorkin and his followers.
