BIGGEST PIANO

Welcome to a very special concert.

It all starts with one strange thing: The piano is just… way too big.

Biggest Piano is a short, comedic horror adventure. It's supposed to be scary—but probably isn't.

A strange letter arrives at the office of detective Ota. It's from Shoko, a music student and pianist.

The location? A concert hall still in operation. Together with his companions Takeru and Makoto, Ota begins investigating.

Everything seems normal. A little too normal.

And then the piano starts to grow. Something appears—drawn to the sound—something that never stops playing.

It’s scary but funny. Funny, but kind of scary. But really… it’s probably not that scary.

Can you break the curse and save Shoko?

Your senses are the score. The escape is your finale.

The curtain rises on the most unforgettable concert of the year.

Fear plays in fortissimo. Will you ever reach the final rest?

Biggest Piano is a 20-minute horror adventure game that begins with a single, unsettling realization: “Something’s wrong with the piano.”

🎹 Designed for players who aren’t good with horror—this game is spooky, but not too scary. 😅 No jump scares or gore. Just a mysterious, slightly cursed piano. 🖱 Controls are kept simple for accessibility. 🐭 A mouse-only mode is available so you can even move without touching the keyboard.

Great as an introductory horror game for first-time players.

And it's totally free—so give it a try and enjoy the concert! 🎵

Two big endings!

Simple controls: Move with WASD, look with your mouse!

Big laughs and thrills—for free! (It's a birthday gift for the developer’s daughter!)

Note: This game was developed somewhere between horror and comedy. Occasionally, the piano may grow to a size not intended by the developer. If this occurs, please report the piano size in your review.
