Underworld Idle

Underworld Idle is an idle game about underworld management.
The basic mechanics: higher-order units create lower-order units. If you've played games like Swarm Simulator or Antimatter Dimensions, you should be familiar with these mechanics. However, in Underworld Idle I present my own take on these mechanics.Game FeaturesFactions (demons, undead, utopians, and blackseekers). Each faction is responsible for producing its own resource.
Mechanics of creating units. For example, higher demons create lower demons, and so on. The same about units of undead, drowners and warlocks.
Infinite progression. Start with a small number of resources and expand into a long list of units and huge numbers.
Infernal Contracts - Prestige Mechanics.
A variety of locations: lab with energy crystals, junkyard, library with grimoire (containing dark spells).
