The game mechanics are a lot like in a "standard" adventure game (examine objects, visit various locations, talk to people, make decisions), but the plot centers exclusively around your relationship with the girls. The game has its own internal clock. You can move around your character on a "city map", visiting different locations. Every visit takes 20-30 minutes of game time. You can make appointments and visit various places at a specific time. The decisions you make influence the story.
