While neither the games nor the bonus illustrations contain any brutal or gore scenes, they do include elements of body expansion/inflation, weight gain/fattening, bursting (comedy-style), as well as some ryona and body modification themes.

The games feature a unique format for RPGs, coming as a 2-game fun pack: You select your opponent in a fighting game-style format and defeat them through RPG-style combat; clearing all opponents will complete the game. (Note: One of the games features a separate final boss.) Additionally, in one of the two games, you can choose a visual novel-style mode where you move between locations to find and defeat your opponents. In either mode, you can freely choose your player character and replay as many times as you like, allowing you to enjoy hours of gameplay depending on how you choose to play.
