Echo Harvest

Move once. Bloom twice.

Echo Harvest is a polished two-minute single-player time garden. Guide a firefly through living light while every route you travel returns eight seconds later as a playable echo. Plan loops, collect blooms from two timelines, trigger Sync multipliers, survive escalating hazards, and chase a better rank.

HOW TO PLAY

• Move with WASD, arrow keys, or the mouse.

• Press Space for a rechargeable burst.

• Your first echo appears after eight seconds; a second joins later.

• Collect the same area across timelines to build Sync streaks.

• Survive for two minutes or restart instantly after a fail.

FEATURES

• Full game loop in about two minutes

• Procedural Canvas visuals and synthesized browser audio

• Keyboard and mouse controls

• Local high score

• No login, backend, API key, install, or paid service required

• Complete MIT-licensed source and README included
