Read full descriptionHide full description
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.
