Assign a Goon to the Floor

Goon

Rooms produce gold/souls/arcane or harvest stone/ore/gold when they have goons working in them
When you build up or down, you begin with a room that produces nothing; try remodeling for a better room type
The Phantom Lord is immortal and will be reborn if he dies
Tap on corpses and skulls to harvest souls and loot gold
Always keep your floors filled with goons working
A mine with no natural resources left will harvest stone
Arcane knowledge increases the health and power of the Phantom Lord
