RESTORE THE RHYTHM OF THE UNIVERSE In a world that has fallen into absolute silence, you are the spark. Echo Factory is a minimalist, audio-visual incremental game where your goal is to rebuild the audio spectrum from scratch.
Start by generating simple waves. (Accessibility Update: No mouse clicking required—press ANY key on your keyboard to produce Echoes!) As your resources accumulate, you will construct a massive factory of sound, turning a quiet void into a symphony of neon lights and frequencies.
AUTOMATE & MAINTAIN THE SYMPHONY Why click when you can engineer? Unlock and build advanced machines like Resonators, Amplifiers, and Harmonizers. But beware: machines degrade.
Introducing the System Diagnostics layer:
Active Maintenance: Corrupted sectors will drop your efficiency. Extract them into your buffer and patch the system.
High Risk, High Reward: Fill your buffer and trigger OVERCLOCK to double your production—but prepare for a massive wave of system errors!
Hire Engineers: Automate the repair process with dedicated engineers and upgrade your Firewalls and Shields to protect your factory.
DEEP STRATEGIC PROGRESSION This isn't just about watching numbers go up. Strategy matters.
Frequency Tree: Customize your playstyle in a massive, branching skill tree. Will you focus on active power, passive automation, or offline efficiency?
Synergy Upgrades: Don't just upgrade everything blindly. Combine specific machines to unlock powerful synergy multipliers.
Rebuild The Core (Prestige): When progress slows down, trigger a cosmic reset. You will lose your machines but gain Frequency Memory—a permanent currency that allows you to push further and faster in the next cycle.
KEY FEATURES
Satisfying Gameplay: Experience the dopamine rush with rhythmic visual feedback, floating texts, and screen-shaking particle bursts.
Neon Synthwave Aesthetic: A vibrant visual style accompanied by a soundtrack that builds up layer by layer as you unlock new technologies.
Offline Progress: Your factory never sleeps. Earn Echoes even when you are away.
Infinite Scalability: From thousands to quintillions—push the limits of mathematics.
Can you break the silence?
