## What is CoinEcho?

Your past moves with you.

Coin Echo is a minimalist physics puzzle about planning trajectories across time. Launch the coin, record its six-second path, and save that run as an echo. On your next attempt, the echo replays beside you—turning every useful route into part of the solution.

HOW IT WORKS

• Pull back to aim and launch
• Watch the coin bounce across rails and walls
• Save useful trajectories as echoes
• Guide specific echoes through resonance nodes
• Reach the goal while every required node is active

WHAT MAKES IT DIFFERENT

• Solve puzzles by cooperating with your previous runs
• Learn from every launch instead of simply restarting
• Discover ten handcrafted levels with increasingly layered timing challenges
• Enjoy precise physics, focused visual design, and responsive sound and haptics
• Play offline with no account required

A path does not disappear when it misses. It comes back to help you.
