Single-finger orbital-defense arcade. Your drone orbits a fragile space station and auto-fires at incoming hazards — tap to flip the orbit direction, that's your only control. Each stage layers in new threats: glue bombs you must shoot at range, homing suicide drones you can't miss, EMP drones that silence your auto-fire on contact, healing orbiters that protect bosses. Six upgrade tracks shape your build. 30+ stages, multi-boss waves, plus a fresh daily challenge for bonus scrap every day.
