Underworld Idle

Underworld Idle is an idle game themed around running a monster dungeon. Basic resources include gems, souls and mana, which are generated by different faction of monsters. Each monster can either be created directly, using various resources, or created by a higher monster of the same faction. For example, Haagenti will create Dantalion, which will create Agriel, which will create gems. Other mechanics, such as runes, energy, and the junkyard, will unlock over time.
