Monster Girl Factory [v0.4.1] [Quiet Crucible]

May 24, 2026F95

Overview:
Monster Girl Factory is a chill incremental crafting game where you build a living factory full of cute monster girls.
Place cute monster girl cards on a 6×6 board. Producers generate resources, Storers hold them, Converters transform one type into another, and Buff creatures grant powerful bonuses when their rotatable sides match with neighbors (Resonance).
Start small, freely rearrange your girls, and watch your production snowball. Socket colorful Gems into your creatures for permanent upgrades, summon fleeting Echo Orbs for huge bonuses, and trade with the charming Merchant who levels up with you.
Upgrade your monster girls to unlock stronger stats and their fully Lewd versions. The more you play, the more automated and satisfying it becomes.
Your ultimate goal: complete the entire bestiary, master your board layout, and collect every monster girl along with her full set of art.
