About the Game

After hours of walking, you finally spot the sign. The Slime Sanctuary. What's left of it, anyway. The forest has taken most of it back. The roofs are caving in. The paths are overgrown. And standing behind the front counter, looking just as surprised to see you as you are to find anyone here at all, is a small slime named Peach.

Slime Sanctuary is a cozy visual novel with light management. Day by day, you restore what's left of the sanctuary, get to know the girls who end up staying, and find out what this place once was, and what it might still become.

Restore the sanctuary, earn mana through its different areas, and spend it on repairs and upgrades as you slowly bring the place back to life.

Features

Fully hand-drawn - every background, character sprite, and CG is drawn from scratch. No AI, anywhere.
3 areas to restore - the main hall, your room, and the dormitory, each with upgrades that change the space.
3 hand-drawn CG illustrations - unlocked as the story progresses, viewable any time in the gallery.
Light management layer - manage the sanctuary, generate mana through different areas, and spend it on repairs, upgrades, and new facilities.
In-game tutorials - each new mechanic is introduced gradually with on-screen guidance the first time it appears.
Linear story, no choices - just a story that moves at its own pace. Follow along.

Meet the Girls

Peach - She's been at the sanctuary alone for decades, waiting for a mentor who never came back. She kept the place standing as best she could, one repair at a time, until the repairs piled up and the people stopped coming.

Mint - She showed up one day without much explanation and made herself useful before you'd even thought to offer her a job. She needs to keep her hands busy, hates leaving things half-done, and will scrub a floor at dawn if it's been bothering her.
