For Cachipun With Waifu Furry Edition , v0.1 probably allows the player to challenge one kemono-style waifu to a best-of-three Cachipun match. Winning might display a “heart” or increase an affection meter, while losing results in a playful tease animation. The “-Sti D...” suffix could be the developer’s signature — perhaps “Sti D.” stands for “Studio Digital” or a username like “Stitches Dragon”.
