## What is Asterhythm?

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.

*The songs above become playable as you progress through the game.


■ An original story of a girl who became a star

Encounters and farewells, revealing her past…
…Could she find out why she became a star?

### 5/5 — プレイしながら寝落ちれるくらい雰囲気が良い

*2026-08-29*

音ゲーはプロセカくらいしかやったことがなかったがすぐに慣れることができて最高に楽しめている。
チルゲーと調べて音ゲー出てきた時には困惑したけど入れてみたら雰囲気最高で大喜びです。
課金の楽曲も購入して楽しみつくしているからこれから追加される曲にも期待。

### 5/5 — 美しき神ゲー

*2026-08-28*

ストーリーがとても好みでした。これからにも期待です！

### 5/5 — 今後に期待

*2026-08-27*

曲数が増えたら面白くなる

### 5/5 — すごい綺麗で楽しい

*2026-08-26*

レーンがない為いろんな所を見ないといけなく難しいですが、その代わり演出が凄いです。景色好きの私にとっては特に響いた音ゲー
楽曲を他にも追加したり、マルチプレイも出したらもっと面白くなって、人気になると思います！！

### 4/5 — 楽曲

*2026-08-21*

ゲーム性や操作感は文句のつけどころが無いくらい満足しています。ただ仕方ないこととはいえ曲が少ないのと、他のゲームとは違い、その少ない曲の中でフリー音源が多いと感じました。YouTubeの動画でよく流れている音源なのでこのゲームの雰囲気にもあまり合っておらず、そこだけが残念です。今後追加されていくであろう楽曲に期待したいですね。

### 5/5 — 神

曲追加お願いします！！！！(できれば無課金のやつで...🙏)

### 5/5 — Hello, I’m korean

*2026-08-19*

다른 어플을 찾는 중에 우연히 발견하게 되었습니다. 처음엔 무시하려 했으나 어플이 주는 몽환적인 느낌에 이끌려 무작정 깔게 되었습니다. 전반적으로 게임의 모든 부분이 저의 마음에 듭니다. 주인공의 이야기, 대부분의 음악, 리듬게임을 처음 접한 저에게도 매우 쉬운 난이도 등등. 그러나 한국 유저가 거의 없는 탓인지 게임 내에서 한국어 버전을 지원하지 않는게 매우 아쉬웠습니다. 스토리의 전반적인 이해를 하기에는 무리가 없었지만, 내용을 깊고 진정으로 이해하기에는 언어의 장벽이 존재 했습니다. 비록 한글 번역본이 나오지 않더라도 저는 이 게임을 계속 플레이 할 것이지만 이후에 가능하시다면 추가해주시면 매우 감사 할 것 같습니다. 또한 노래를 온전히 즐기고 싶기 때문에 점수에는 반영이 되지 않고 클리어한 맵에 한정하여 오토모드를 추가해주시는것도 좋을것 같습니다. 긴 글 읽어주셔서 감사합니다.🙌

### 5/5 — 期待しかできない

*2026-08-19*

とても雰囲気が良く音ゲーとしても完成されてます。私は滅多にレビューを書きませんがとても期待しています！

### 5/5 — 普通に楽しい

*2026-08-18*

だが、曲は少ないのは結構痛いところ。
でもそれ以外は普通に最高。
迷ってるなら絶対やった方が良い
