Developed by: AlfaSystem
Published by: Casio
Bow-wow Puppy Love Story is a simple Japanese-style adventure game designed for young girls. The majority of the game consists of written dialogue with cute animated characters. There are dialogue choices every so often, though they have only a minimal impact on the story progression. The player can also jump back to specific scenes, and print a variety of stickers with images from the game.
This is one of the most common games you can find for the system.
Other details
This is the only game for the Casio Loopy to feature voiced samples.
It does so by embedding an ADPCM soundchip onboard, which then passes it through the console's audio output.
