Loopline-switchloop

Loopline is a portrait arcade survival game built around one simple rule: every line you draw can save you or trap you. Drag with one thumb to pilot a neon runner through a collapsing signal grid. Your trail damages enemies, cuts lanes through swarms, and gives you the space needed to charge relay towers before the route folds in. Each run is short, sharp, and build-driven: - Carve glowing trails through enemy packs - Charge three relay towers under pressure - Trigger Dash and Pulse tools when the screen gets dangerous - Draft upgrades across Trail, Pulse, Dash, Survival, and Pickup families - Stack synergies into stronger run builds - Extract before the signal collapses The free route lets you play the Relay Yard loop. Full Run is a one-time unlock that opens Prism Flood Channel, premium upgrade capstones, elite pressure, and the Null Warden boss branch. No accounts, no ads, no online login. Just a fast neon survival route designed for one-thumb play.
