Omakase! Savers is a comedy adventure game featuring live-action scenes. The player takes the role of the girls' classmate, who appears as a small ghost, and must guide the girls in their quest to seal the spirits again and restore their classmate to his human form. This primarily takes the form of exploring the town on foot, talking to the townsfolk and investigating to find the whereabouts of the spirits causing trouble. Occasional combat takes a semi-real-time format, with the player moving around freely but pausing to perform attacks.

The game is divided into four chapters, each focusing on a specific spirit that must be defeated and captured. The characters in the game are represented both by anime-style sprites and digitized photo portraits of real actors, while numerous live-action cutscenes drive the story.
