Twin Switchyard is an original synchronized platform puzzle. Guide an otter and a mountain goat through split lanes, flip signal gates, and gather every relay shard together.
Two route keepers share one signal line: the otter handles the low lane while the mountain goat takes the high lane. Each switchyard asks both travelers to move through the same moment without leaving one behind.
The two characters advance from one shared input. Left and Right move both travelers across their separate lanes, while Jump gives both a timed hop. A gate can open one lane and close the other, so the useful route is always a coordination problem rather than a solo run.
Relay shards are collected only when the correct traveler reaches them. A hazard collision resets the current stage attempt, while a clean route through every shard and the exit advances to Result. Stage progress and local best move counts stay in this browser.
Six authored stages begin with one clear split and a forgiving jump. Later stages add alternating gates, moving hazards, staggered shards, narrower landing windows, and combinations that require both travelers to arrive at the exit together.
Twin Switchyard keeps one logical play space across phone, landscape, and desktop. Its shared movement, lane-specific hazards, touch buttons, mouse activation, and keyboard controls resolve to the same state, while Main, Stage, Battle, and Result remain separate screens with direct returns. The complete interface uses one centered logical layout with a 920-pixel maximum. Phone, landscape, and desktop views scale the same controls, hit areas, artwork, and game coordinates together instead of stretching individual pieces. Touch, mouse, and keyboard therefore act on the same legal state. The Main poster and Start Game action remain separate from Stage management, while Stage selection, Battle, dialogs, and Result keep their own bounded content and return path.
This General browser game has no account, purchase, chat, leaderboard, or advertising flow. Stage clears, best move counts, language, sound, and preferences stay in the current browser profile and may reset when site data is cleared. You can play without creating an account. Progress is saved in local browser storage on the current browser profile, not in an online account or cross-device database. Clearing site data, using private browsing, changing browsers, or moving to another device can create a separate save or remove the existing one. Language, sound, and reduced-motion preferences follow the shared WeightPlay controls when the browser permits storage. No guide result is a medical, school, or professional assessment.
