Bikkuri Mouse1)—perhaps the Sony PlayStation 2's first mouse compatible release—is a drawing game by UrumaDelvi, and 岩井俊雄 (Toshio Iwai). UrumaDelvi also contributed to Iwai's simtunes.
Bikkuri Mouse is a drawing game probably aimed at children. The player can select from twelve colours, different brushes, and different drawing modes. Certain colour and shape combinations act as macros. For example: a yellow circle may produce a sun. It allows for two players to draw on the same stage.
