How is your game related to the Theme and Special Object?
This game a 2D Shooter, and is about people who have been riding in an air balloon, where their balloon malfunctioned they then crushed in an area where monsters are teeming, the player are sent to the location of their last signal received from their GPS to rescue them before the time runs out and they are eaten by the monsters.

In short I used the theme and the special object in the setting of my game, not in the mechanics or any sprites! :D
