Trace each plane to its matching runway and keep the paths from crossing.
Planes drift in from the screen edges, each colored red, blue, or green. Drag your finger from a plane to the matching runway, and it flies the path you traced, but if two routes cross, those planes collide and the run ends. The sky fills up as you climb: faster spawns, express flights, and a timing window that rewards a clean landing. Coins buy three mid-run boosters (double score, slow motion, clear the board) and new plane shapes in the shop, while 32 levels each set a score goal with a one to three star rating.
