■ About This Game

EEL KNOW: Perfect Pitch is a new kind of pitch quiz game where garden eels—the mysterious, popular aquarium fish loved for their round eyes, goofy expressions, and the cute way they poke out of the sand and sway—stretch and sink to the notes. Before you know it, playing with these garden eels will naturally train your sense of pitch.

The higher the note, the farther they stretch. The lower the note, the shorter they stay.
Use this as your clue to find the correct note for the glowing eel on your keyboard.

It’s cute, yet a little surreal.
And the more you play, the more it tests your ears and memory in this new kind of pitch puzzle.

■ How to Play

Listen to the reference "Do" (C) note.

A classical melody plays, and the garden eels stretch out one by one.

Guess the pitch relying purely on their length.

Wait too long and they slip back into the sand—testing your memory too.

Miss a note, and you get a hint: "Higher ↑" or "Lower ↓".

Keep a streak going, and the eels in the back will dance and wiggle to celebrate!

■ A New Puzzle: Guess the Pitch by Length Alone

Intuitive UI: White keys = white garden eels, Black keys = striped garden eels.

A unique cast of friends: Each eel has its own tempo, sound, and stretching style.

Field Guide system: Build trust to upgrade their frames from Bronze → Silver → Gold → Rainbow.

Bite-sized sessions: Play a song in a few minutes—perfect before bed.

All classical music used is in the public domain.

White Eels, Striped Eels, and a Unique Cast of Friends
The white garden eels handle the white keys, and the striped ones take the black keys.
Even with the same melody, the game feels completely different depending on which friends show up.
Some stretch slowly and sink slowly.
Others slip back into the sand the moment they reach full height.
Chinta, Genta, Kirata, Shinota, Gonta...
Which friends will you meet today?

■ A Field Guide That Grows as You Play

Clear a stage, and the garden eels you met are added to your Field Guide.
At first, some might just be silhouettes, or lack a frame entirely.
But meet the same eel again and again, and they will start to trust you.
Their entry frames will upgrade from Bronze to Silver to Gold, and finally to Rainbow.
A field guide where running into duplicates is a joy.
Take your time and collect these gentle friends of the sea.

■ Play for Minutes, Perfect Before Bed

Just one song before bed.
Just one eel to clear your mind.
Come on by and see them.
As you listen to classical melodies everyone knows and guess their pitches, your ears and memory will gently level up.
Why not test your pitch in this soothing sea?
