Unlike previous Illusion soft games the clothes opacity can be modified instead of the style. The player is limited to modifying the clothes to 50% opacity when he starts out. If the player chose a female avatar, the player is able to modify her breast size. When the player enters the environment, the objective is to progress through one of the two three-part storylines. There are two camera modes on the top right corner of the screen which is the female camera (in pink) and the players camera (in blue). The two storylines is dependent on the avatar the player chooses. To progress on the storyline the player must find items in the environment and use them on the female character in a sexual manner.
