About This Game

Follow the music. Fill a page with a story.

From familiar classical melodies to lively ragtime and original pieces, tap along to the beat as letters, reflections, and short stories unfold on paper.

Find your way to play

Focus on the beat with one key, split the rhythm between two keys, or enter the English text yourself in typing mode. Choose your input style and difficulty, settle in for a song, or push for greater accuracy and longer combos.

A stage that grows with you

Earn points through play to collect keyboard housings and keycaps, then combine parts and colours to build a keyboard of your own. Complete goals to earn decorative objects and arrange them to make the stage yours too.

A record of each performance

In typing mode, wrong letters and missed inputs remain on the page as typos and gaps. Look back over your results, then try again to beat your records. Collect certificates for different songs and difficulties as your performance history grows.

Create your own charts

Use the built-in editor to create charts, then import or export them as .keycerto files.
