You run Earth's launch pad. Hold to choose an altitude, let go to launch. Satellites that meet in the same orbit dock into bigger ones: cubesat, comsat, telescope, lab, station, ring habitat, Gateway. Every lap they fly pays you. Cross two orbits and they collide. The debris keeps orbiting and shreds whatever it meets next. When the debris wins, the sky closes. That is the Kessler syndrome. It is your fault. You will want to go again. ONE THUMB - Hold anywhere: the marker climbs the orbit shells. Let go: launch. - Release with the arrow straight for a clean circle; release off-centre for an ellipse that crosses traffic. - The path preview turns red when it will cross an occupied shell. Every crash is a choice you made. BUILD THE SKY - Same shell, same kind: they dock into the next tier. Seven tiers, from a cubesat to the Gateway. - Build a Gateway and the Moon comes online: double income for the rest of the run. - Three daily contracts give every run a purpose beyond the score. DAILY SKY - The same satellite queue for everyone, once a day. One attempt counts, practice is unlimited. - Share your sky as a spoiler-free card. Beat your friends on the leaderboard. HONEST AND LIGHT - Plays offline. Progress saves on your device. - Free. Optional ads only: watch one to send the Sweeper drone or double your coins. - No account, no login, no permissions beyond the basics. Hand-drawn pixel art, original music and sound. Built by a small studio that wanted a space game you can understand in one second and play for a month. How long can you keep the sky open?
