Neko Mamma EX is a collection of four small games, unrelated by genre, story, or theme - with the exception of omnipresent adult content:
- The longest of the games is a very simple dungeon crawler; the protagonist explores a pseudo-3D maze, fighting randomly appearing enemies in turn-based combat and gradually leveling up. The enemies are pretty young women who undress upon defeat.
- A so-called “Battle Quiz” is a striptease trivia game in which the player must answer a series of questions within a time limit. After each successful round the virtual female opponent removes a part of her clothes.
- In the “Cat Race” game the player gambles, betting on various feline-themed attractive women who take part in a running competition. The player can choose between four different courses.
- A very short Japanese-style adventure game with minimal interface, in which a young girl consults a psychologist and receives a somewhat unusual treatment.
In addition, Neko Mamma EX features a music room, “making of” information, and an art gallery with mostly unrelated, often erotically-themed images.
