Lonely Time for Mac

From iDevGames:

Set in Japan, you are a typical business man who came home from work one evening. You find your pet cat missing, and so you run out of your home and search the city with pet food in hand. As you search for your cat, you can visit many locations in a typical Japanese city and interact with the natives. (Click on various objects and characters.) This is an original Japanese game localized for English gamers. (ie. It features your typical Saturday morning Japanese monster movie translation bloopers.) If you enjoy this game, check out my other game "Samurai." -- Takeshi Sakai
