Nintendo (PK: NTDOF) has released its highly-anticipated debut smartphone game, Miitomo, in Japan.
The app is a social game in which players create an avatar known as a Mii and share posts with friends from Facebook and Twitter.
Players are encouraged to answer questions about their likes and dislikes and the answers can be seen by friends in the app.
Early reviews of the app have been mixed. Video game site IGN said Miitomo had "a lot of potential" but had "missed opportunities with the lack of room customization".
Technology site The Verge said Miitomo was "a little clunky at times, with too many load screens" but did have an abundance of "sleek, appealing quirkiness".
But hundreds of other reviews on the Japanese version of the iOS app store have been largely positive.
Miitomo lets players dress up their avatar with Nintendo-themed accessories and share pictures of their Mii with friends.
Nintendo shares last traded in New York at $142.00 U.S. within a 52-week trading range of $122.91 to $204.26 U.S.
