StarhandProtocol2 vs CoinEcho

The starship is drifting into an unstable quantum sector. Its systems can only be restored through the Starhand Protocol—a tactical simulation where every poker hand powers the next stage of your journey.

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.
