Idle Space Farmer - Waifu Manager Simulator for Android
The player's task is to develop underground bunker systems on different planets. When the player opens a new level of bunker he is attacked by mobs, which must be constantly killed by specially hired agents. The latter can be upgraded by a variety of characteristics for money.
The money is earned by getting resources at each underground level. That's what the agent is protecting. In order to increase the cash flow, it is necessary to develop logistics - elevators, ore carriers and other such.
