Rooftop Signal

Rooftop Signal is a polished offline line-of-sight puzzle game set above a communications blackout. Place compact rooftop relays to reconnect emergency hubs across forty handcrafted city puzzles. Every device has a purpose. Relays are efficient all-round links, directional antennas reach farther, reflectors redirect beams around awkward rooftops, boosters cross long gaps at higher power cost, and one-way transmitters reward precise orientation. Billboards, water tanks, towers and rooftop height differences can block a route, so every placement matters. Restore four atmospheric districts across day, sunset, rain and night chapters. Complete each network to unlock the next rooftop, then replay levels to earn up to three medals for full connectivity, minimal device use and low power consumption. Rooftop Signal includes a first-level field tutorial, a district restoration map, persistent local progress, pause and restart controls, sound and music toggles, optional haptics and a Reduced Effects setting. Everything works fully offline after installation. There are no ads, subscriptions, in-app purchases, login requirements, analytics, trackers or network features.
