Ka Japan

In Mister Mosquito, players enter the virtual household of the Yamada family in the role of a tiny, uninvited guest. According to the game's introduction, the title character needs to drink as much blood as he can to be ready for winter, but his suburban hosts are not the most willing donors. In fact, the Yamada family members would like nothing better than to swat him out of existence, once and for all. The rules for survival quickly become clear: Keep hidden, don't get squashed, and watch as the family's frustration level grows.
