The description of the game may need a rework.
“The basics of the game is that the player, as a village administrator,
explores dungeons for the sake of the village's happiness and prosperity,
and uses the supplies and babies obtained there to run the village.”
Because the protag (if we can call it one) doesn't look like a village admin, since there is no village (just a house with a big underground part), no villagers (besides people in captivity), mostly no happiness (except if you count the globins, but I personally wouldn't), and no supplies… well not in the most normal way.
It would be an interest take on lore.
For example ,
The setting could be player (man or boy shota) was exiled and forced to become chief of a ruin down fort that get raid by monsters daily.
-Player start with some common female soldier (sword and archer) and player have to mate with them to product more soldiers.
-The units have 2 stage , when new born baby get breast feeding enough , they will turn into girl , and when they drink the milk (product by mature female) they will become mature.
-Monster who come to raid your fort will drop materials when defeated , something like wood and stone (or just gold) to upgrade your fort and buy items or weapons/monster meat to upgrade female unit stats
-When a monster defeat an unit , it will mate with her on spot and then kidnap her (and you lost that unit).
-Some unique monster use female like meat shield and they drop female unit when defeated.
-Player can create party to raid monster lairs to save more unit
-On ground fort have player's room (mating room) , Tavern - where you can hire (buy) random units or buy item from merchant NPC , Clinic to heal wounded units (4 at max) and other rooms. Mercenary base where you can "sell" the extra unit for cash , training room (sexually) with machine like the capsule .
After 5 days , a new NPC will join you and unlock new system (like in MBM)
-underground have unit building x5 units (like in MBM) , delivery room , breast feeding room , milking room ( product milk) animal breeding room (product meat for gold) tentacle room (unlock after Rune come). Some building only use max level sexual training unit.
I prefer the unit room of MBM instead of new system , since you can easier to manage and keep control of units.
After you have enough tentacles eggs (product by rune) you can use them to unlock monster lair. Monster lair is a safe place (only able to build underground and without get raid) and you can breed female unit with monster to product monster girls to protect the main fort.
Rune is manage the monster (mind control them) and you can kill the monsters for drop (aka butcher)
Also you can add mind controlled NPCs and add them to monster lair like in MBM.
What do you guy think about this type of setting ?
