What is Skull Up?
Skull Up is an idle strategy game set in a playful underworld where you start as a weak skull and slowly grow into a true ruler of the undead. The core of the game is collecting quirky Skellies, building teams that actually feel different to use, and deciding how they work together in battles and management tasks.
