3L is a timing-based signal routing game set on randomly generated alpine communication maps. You never steer a character. Instead you open and close mountain relays so automatic pulses can travel from a transmitter to a final station through a living network of towers.
Each level rebuilds the station layout, link graph, and pressure pattern. Multi-path masts force quick connection swaps. Higher peaks introduce weather blackouts, temporarily offline towers, signal amplifiers, drifting mobile stations, and rare solar crystals that restore the full network for a score surge.
After every run you see delivered signals, average transfer speed, best streak, and your all-time record. Local statistics, achievements, a leaderboard, and audio-vibration settings support long-session play. The 3L core experience is Signal Network: a precise, replayable chain-building challenge defined by procedural peaks and split-second relay control.
