お姉さんのいる屋敷 RUIN'S HOUSE
A unique fusion of "Lady" × "Haunted Mansion"—a 2.5D horror action experience emerges! Who is the lady? What happened in this place long ago? Collect the scattered Fragments of Memory throughout the mansion and uncover the truth!
"RUIN'S HOUSE" is a 2.5D horror action game where the lady and the mansion are deeply intertwined in its unfolding narrative.
Experience both a dark, emotional story reminiscent of 2D horror games—brought to life through pixel art and illustrations—and immersive 3D horror action.
Story
Synopsis
Meguru loses their way and arrives at a mansion where a mysterious lady resides.
She offers them a place to stay—but when night falls, the lady vanishes, and the mansion transforms into a nest of danger, where hostile creatures roam.
Direction & Tone
To keep the experience accessible and enjoyable, horror elements—such as story sequences and enemy encounters—are deliberately kept subtle.
This game focuses on atmosphere and emotion rather than overwhelming fear.
Gameplay Systems
Exploration
Reach the goal within a mansion whose layout changes with every playthrough.
Use items and environmental mechanics to gain the upper hand as you explore.

These Materials can be used to craft items and disable traps.
Upgrades
