A hard rhythm game.

Notes fly in from four – or eight – sides and hit the star on the beat of your music. Play songs from osu!, Beat Saber, Geometry Dash or any mp3 – STARLINE turns them into maps.

STARLINE gameplay: notes fly towards the star from four sides

What's in STARLINE

Easy to learn, hard to master. Every note lands exactly on the beat of the song.

♫

Your music

STARLINE finds your osu!, Beat Saber and Geometry Dash songs by itself. Drop any mp3, ogg or flac into the songs folder, or import .osz files.

!

Rhythm maps

Notes follow the music: calm parts are slower, choruses get dense. Everyone gets the same map for the same song, so scores are fair.

+

Mods

Double Time, Half Time, Hidden, Rotate (the whole field turns and the lanes swap places), Sudden Death and NoFail. Shifty is in beta.

✦

4 or 8 lanes

Play with four keys – or switch any map to eight lanes with diagonals. Hold notes, double taps, spins and speed changes keep it fresh.

#

Replays & leaderboards

Every run is recorded. Beat the best score on each map and climb the leaderboard.

⌨

Your keys

Bind every lane to the key you like – each key only once. Note lock means spamming does not work: timing counts.

Screenshots

A calm, dark interface with soft cards and one colour accent at a time – no neon.
