Help Skeletor to rebuild his evil lair, Snake Mountain! 

Rooms 

When you have earned enough gold, tap the + button at the top of Snake Mountain to rebuild a new room. 

A room may belong to either a fellow villain or a hero. Building a villain's room recruits them and unlocks their perk, while building a hero's room unlocks a new run for Skeletor. 

Items 

You can earn pieces of items by opening Skelepacks, which are earned through the Evil Pass. Once an item is complete, you can place it in a character's room but hitting one of the + buttons in their room. 

To remove an item, tap the placed item and select the "Remove Item" button. 

Collector Score 

The more items you collect, the greater your collection score. Leveling up your collection score increases your run multiplier.
