About this game
What if I told you that you could save the world, defeat the demon lord… while being pregnant in the process? What... sounds ridiculous?
Meet Marie!
A fledgling adventurer from a small village who just got roped into the weirdest hero's journey imaginable.
After a sudden turn of events, Marie is gifted with a strange blessing that makes her extremely fertile. As a result, she will be guaranteed to be pregnant every time she had sex, and her pregnancy progresses at Mach 2 speed!
Oh wait, did I mention she chose a cow-print bikini as an outfit, for absolutely no reason?
Despite being blessed with such unique power, it helps Marie make new friends and even outmatch the demon army. Not exactly sure how that works, but hey, if it helps save the world from chaos and extinction, who's complaining?
Defeat the demon lord? World repopulation? Great sex partners?
Marie and friends are all you need!
Marie's Adventure is a light-hearted yet mature fantasy RPG that blends humor and a dash of chaos. Have sex, battle demons, birth a new generation of hope, and maybe, enjoy the ride a little too much. All while navigating pregnancy, passion, and a cow-print bikini she refuses to change (don’t ask).
Along the way, you’ll navigate a story filled with emotional moments, spicy encounters, and more unexpected turns than Marie’s ever-ready fertility cycle.
Enjoy a brand new H-RPG experience crafted with passion and care, featuring a fully customized UI designed for smooth exploration and combat, unique event systems, and a progression system tied directly to Marie’s growing legacy (and belly).
Pregnancy-Driven Progression – Fertility and pregnancy as a core game mechanic. Give birth to power up Marie and her allies!
Dynamic Turn-Based RPG Battles – Experience a battle system that feels classic yet fresh. Shape your strategy through preparation, smart decision-making, and adapting to ever-tougher challenges!
A Wholesome, Hilarious, and Sometimes Horny Story – Follow Marie’s journey from small-village sweetheart to world-saving (and world-repopulating) Scion. Enjoy a narrative filled with lovable characters, heartfelt moments, unexpected twists, and just the right amount of lewd chaos.
Brothel Work & Hidden Desires – Out in the world, Marie may be sweet, but when it comes to sex, something deep inside her awakens. As she takes on brothel work, her “sluttiness level” slowly rises — reflecting a side of her that only comes out in the heat of the moment.
Dynamic CG System – All CG scenes and art adapt to Marie’s current belly size. From flat to full-term, every moment grows with her.
The World is Yours – Whether you're navigating through the story, battling demons in dungeons or servicing clients at the brothel, the choice is yours. Customize your experience with optional content settings — including birth scenes and x-ray views — all toggleable through the in-game menu to suit your comfort level.
Cow-print Bikini – We don’t know why either. But it’s iconic now. 🐄
