Brain Limit: Missile Launcher's Feelings app for iPhone and iPad

Imagine that you are a targeting system of a multiple-missile launcher.
In order to pursue missions to defend the earth from the attack of alien crafts, you have to track multiple enemies simultaneously.
The peace of the earth depends on your ability in visual attention.

===============================
Psychologists have conducted multiple-object tracking (MOT) experiments to investigate visual attention.
In this app, the psychological experimental task has been transformed into a casual game. Your achievement in this game (high score) is sent to the GameCenter. Your rank in the GameCenter may suggest your level of visual attention compared to other players
