お姉さんのいる屋敷 RUIN'S HOUSE

"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.

• Materials

Destroy objects or defeat small enemies to obtain Materials.

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

• Upgrades

Bring back materials collected in the mansion to strengthen your character.
Increase attack power and stamina, and craft special charms that grant unique abilities.

• Difficulty

Even if you are defeated inside the mansion, you can continue while retaining your progress.
This allows players who are less confident with action games to enjoy the story at their own pace.

After clearing the game once, Master Mode is unlocked—a challenge mode with no continues.
