Fold a paper plane. Point it at the edge. Tap, and off it goes — whoosh. Every board is a small logic puzzle. Planes only fly when the lane ahead is clear, so the order you send them in is the whole game. Turn the weather vane and a plane follows the arrow instead. Turning is free, so try it as often as you like. The cracked floor is not free: one plane crosses it, then it breaks and the tile is closed for good. Choose who gets it. • 400 hand-checked levels across 40 chapters, then an endless mode • Every level is guaranteed solvable — verified by a solver, not by hope • No timers, no lives ticking down while you sleep • Plays fully offline • Long-press any plane to preview its lane — looking never costs a heart • A checkpoint at the end of every chapter App languages: English, Turkish, German, French, Spanish, Japanese, Traditional Chinese, and Korean. Calm on the surface, sharp underneath.
