Itsudemo! Nyan to Wonderful

"Itsudemo! Nyan to Wonderful" is a Game Boy title centered on raising virtual cats and dogs. Players can manage up to four of these pets at a time, with care routines involving feeding and exercise.

Engaging in mini-games serves the dual purpose of providing activity for the pets and improving their various attributes. Progress in these areas is acknowledged through the awarding of medals for proper care. The game also includes a breeding system, where pairing a male and female of the same species results in offspring.

Using a link cable, players can connect with a friend's Game Boy to either trade their pets or compete against each other in the available mini-games.
