ECHO DIMENSION

Strike the first note, and the world answers.

ECHO DIMENSION is an anime rhythm game where music is your weapon. The world is held together by Resonance — every emotion people feel becomes melody. Then Silence begins to devour it, and wherever it spreads, people can no longer say what's in their hearts.

You are a newly awakened Tuner, able to play back the domains Silence has swallowed.

How to Play

• D F J K — four lanes, tap on the beat
• Esc — pause · F11 — fullscreen
• Judgement windows: ±155 ms (MISS) up to ±55 ms (PERFECT)

Features

• 4-key falling-note gameplay with three difficulties and one-tap audio/visual sync calibration — the game measures your own device's output lag, so judgement feels right on your machine.
• 50 original tracks across 8 musical domains — EDM, rock, Chinese traditional, jazz, exotic, orchestral epic, dark ambient, and piano.
• A complete story campaign with five companions: Rin, Shuang, Jiu, Mu — and Zero, the avatar of Silence itself.
• Full English and Simplified Chinese support — every line of dialogue, not just the menus. Switch anytime in Settings.
• 19 achievements plus a full local save of scores, timing offset and volume.

Languages

English and Simplified Chinese, both with full interface and full story translation. Switch in the in-game Settings page.

A Note on Assets

The character portraits and background art in this game were produced with generative AI image tools, then edited and composited by the developer. All 50 music tracks are original works written by the developer and are not AI-generated.

Feedback

This is the first public release. If something feels off — timing, difficulty, readability — please tell me in the comments. Rhythm games live or die on feel, and outside feedback is the only way I can find what my own hands have gotten used to.

Credits

• Music, code, story, design: Li Gen
• Engine: custom HTML5 / Canvas (no third-party runtime)
