Skull Up is an idle mobile RPG where you play as an undead skeleton rising to become the Skull King. You collect over 60 unique skeleton characters ("Skellies"), upgrade them through a loss-free progression system, and manage resources through idle gameplay while fighting enemies.
Focus on upgrading Skellies that provide resource generation and survivability in the early game, as these will help you progress through initial content and maximize your idle rewards. Since the game has a loss-free progression system that allows full refunds on upgrades, don't be afraid to experiment with different Skellies to find what works best for your playstyle.
