The document describes a concept for a ghost game created in Photoshop. The game would be a point-and-click shooter where the player zaps ghosts through multiple levels and boss fights. The levels are color-coded in the order of the rainbow, from white to violet, and players earn points to upgrade their character's outfit, health, gun, and other abilities. The concept was hand-drawn using a 1-pixel pencil and color wheel in Photoshop.
