LINEA · Rhythm's Thread

Every song holds a landscape waiting to be explored. 

LINEA is a rhythmic journey where your music shapes the world. Upload any track from your local library, and watch as its beats, tempo, and genre weave a winding path through a breathtaking, Monument Valley-inspired low-poly valley. 

Follow the line, tap to the rhythm, and get lost in the music.

🎧 How It Works

1. Upload a Song: Drop in any MP3, WAV, OGG, FLAC or M4A file. 

2. The Valley Awakens: The game analyzes the rhythm and genre in real-time. A classical piece brings a misty dawn; electronic beats summon a pulsing dusk; jazz paints a golden sunset.

3. Walk the Line: Follow the path, tap to the beat to make 90° turns, and collect stardust, notes, and crystals. Stray from the path or hit an obstacle, and the journey ends.

✨ Features

•  🏞 Breathing Valleys: Procedurally generated landscapes filled with drifting clouds, flowing streams, flying birds, and falling petals.
•  🌗 Synesthesia in Motion: The mood of your music dictates the time of day and the color palette of the world.
•  💠 Rhythm Collection: Hit the beats perfectly to build combos, trigger particle bursts, and gather light.
•  🔒 100% Private & Secure: Pure front-end experience. Your audio files are processed locally in your browser via Web Audio API and never uploaded to any server.

💌 A Note from the Developer

LINEA was built as a love letter to music and peaceful journeys. I wanted to create a space where your favorite playlists could become physical paths you can walk on. I hope it brings you a moment of tranquility and a completely new way to experience the songs you love. 

If you enjoy the journey, please consider leaving a comment with the song you played, or support the project via the donation button on the home screen. Every cup of coffee keeps the valley breathing.
