ScanKu is a portrait-mode casual aiming-and-launching mobile game centered around drag-to-charge and precision hitting. Players control a launcher at the bottom, pulling back to charge, then releasing to send out an energy projectile. Hitting the hexagonal crystal targets that move left and right across the upper part of the screen earns points; Consecutive hits trigger bonus points. Missing three times in total ends the round. Targets shrink and speed up as scores rise, tightening the pace. The game supports pause and high-score recording. Easy to pick up, yet requires trajectory prediction and timing, making it suitable for repeated short sessions.
