Arisa | Psychological Horror Game is a 2.5D psychological horror game that tells the story of your younger sister’s mysterious disappearance.

One day, Arisa receives a strange email — a disturbing message that leads you back to the ordinary school you attend every day. But the moment you step inside, one thing becomes crystal clear: Arisa is not alone.

Unlock the truth hidden behind locked doors, dark hallways, and your fragile mind. Arisa blends narrative-driven exploration with atmospheric horror, blurring the line between reality and illusion.

🕯️ Survive the Darkness of the Night
In the middle of the night, you return to the school you know so well, following a strange message. What seems ordinary during the day turns into a nightmare that challenges the very boundaries of reality at night.

🏫 Immersive 2.5D Exploration
Dark classrooms, echoing corridors, and an eerie atmosphere await you. Experience a cinematic sense of exploration with side-scrolling camera angles.

🧩 Narrative-Driven Puzzles and Exploration
Collect fragmented memories of the past and follow the trail of your missing sister. Every piece of information you find pulls you deeper while testing your sanity.

🧠 A Story Blended with Psychological Tension
As you drift away from reality, you start asking yourself: Is my sister really here? The events will test you both mentally and emotionally.

🎧 Atmospheric Audio and Visual Design
Echoing footsteps in the darkness, eerie whispers… every detail draws you deeper into a haunting horror atmosphere.

Hiding is not an option in this game. You must escape from what’s following you. But this thing… it neither kills you nor lets you go. Every encounter turns into a chase.
