Marie's Adventure Wiki

Welcome to the unofficial Marie’s Adventure Wiki — a fan-maintained guide for No Budget Developer’s 18+ pregnancy H-RPG that launched August 6, 2026 on Steam, itch.io, and DLsite. This overview links every major hub so you can jump from first boot to Sylva City Inn births, Church fertility prep, brothel side content, and launch-week hotfixes without drowning in search results.

We are not affiliated with the developer. Game text is English only; wiki locales translate our guides separately. For purchase links, use the header Get the Game button or the official Steam page.

1. Getting Started — day-one route from the starting village.
2. Content Settings — toggle birth, lactation, and x-ray content before story scenes fire.
3. Controls — keyboard, menus, combat inputs, and F5 reload habits.
4. Pregnancy System — why walking matters and sleeping alone does not.
5. Sylva City — the only Inn that completes labor.

Guides & walkthroughs

The Guides Hub (includes Where to Buy, Achievements, Desert Caves) collects deep dives: how to give birth, how to get multiples, troubleshooting, and more. Guides explain why rules exist; maps and tools show where to execute them.

Map & locations

The Map Hub indexes the overworld:

• Sylva City — mandatory birth hub and shops.
• World Locations — starting village, Seliana, Mulshore, Church fertility, brothel districts, demon routes.

Remember: sleeping outside Sylva never triggers birth — intentional design, not a bug.

Builds, characters & items

Combat and growth pages support the birth loop:

• Combat Basics and Party Progression
• Marie character focus
• Artifacts and Fertility Boosts

Tools

The Tools Hub hosts interactive helpers. Featured: Pregnancy Tracker — enter breast milk capacity, estimate litter size, follow Sylva save-scum checklists.

Updates & stability

Launch RPG Maker titles ship rough edges. Track them centrally:

• Updates Hub — patch policy and timeline.
• Known Issues — white/black screens, Windows Defender false positives, Mulshore conversation loops, www folder overwrite hotfixes.
• Release Notes — Aug 2026 1.0 feature baseline.

Review & editorial

Read the Review for launch-week strengths (pregnancy hook, CG adaptivity, tone) and weaknesses (Defender scares, Inn routing confusion, combat depth). Use it to set expectations before you buy.
