SPRay is an action game with a fantasy-based setting in which the player assumes control of a young prince going by the name of Ray. The action of the game takes place in the planet of Ecoia, in which everyone pays homage to the Crystal Sun, which casts its illuminating and energizing rays over the land of light and serves as a source of protection. One day, an evil queen of darkness launches an assault on the realm, shattering the Crystal and mortally wounding the king in the process. Ray, who is not biologically related to the king, is given the enchanted crown of the realm by the monarch before he passes away. Ray is instructed by his father to locate all of the fragments of the Crystal and reassemble it so that it can once again shine with its full brilliance. The crown bestows upon Ray the ability to call upon the assistance of the spirits Liad and Gush.
The player has the ability to spray many sorts of fluids, such as slime, water, vomit, and ice, when they make contact with the spirits Liad and Gush. These liquids can be utilized to do damage to foes or navigate around obstructions. For instance, the player needs to spray water to get through flames. In addition to the typical attackers, there are additional bosses to contend with.
