About this game

A world of stars, radiant yet fragile, where sound spreads out across the sky.
Lights are woven into Constellations, revealing forgotten memories.
"...Please, don't be sad anymore. It's a promise."

A full-screen music game themed on constellations and star clusters, by StrayCubic, creator of TAKUMI³.
Tap, flick, and hold in time with the notes that drift among the stars. Simple controls deliver an entirely new musical experience.

✦ Especially recommended if you…
・Crave the chill, soothing feeling of gazing up at a starry night
・Want to play a rhythm game with calm, gentle tracks
・Feel a little worn out by the relentless pace and intensity of recent rhythm games
・Are looking for a fresh rhythm game using the whole screen

✦ Charts drawn by constellation lines
Asterhythm's defining feature is the constellation lines that connect the notes.
They show you where the next note will appear so you rarely lose your way, and they trace ever-changing patterns in time with the music for a dreamlike, emotional play experience.
From charts that newcomers can enjoy to ones with real bite — and even a hidden difficulty…? — Everyone is welcomed in the starry sky, from beginners to veterans.

✦ Featured tracks
Play songs you may well have heard before, for free.
・2:23 AM / Syarou
・Shining Star / Maoudamashii
・YOIYAMI / Keyta
…and many more, including original compositions written just for the game.
*The songs above become playable as you progress through the game.

✦ An original story of a girl who became a star
Ciellia, woken up in the vast starfields, sets on a journey to find her lost memories.
Encounters and farewells, revealing her past…
…Could she find out why she became a star?
