Nintendo has delayed the launch of its first mobile game until March next year to further improve the application.

Miitomo, the first game from Nintendo’s partnership with mobile gaming firm DeNA, was expected to be released by the end of this year.

The free-to-start communication app lets players create their own Mii avatars and interact with other players’ avatars.

Once the players create their own Mii avatars, they will be asked several questions.

The answers given by the players will be communicated to others, and the interaction between Mii avatars will help users share about themselves to their friends.

Nintendo is planning to release five smartphone games by March 2017.

The company is also planning to launch a new account service, dubbed Nintendo Account, which will work on mobile and PC platforms as well as its hardware devices.

Nintendo’s operating income was ¥8.9bn (about $74m) for the six months ended 30 September 2015.

Net sales increased 19.1% to $1.69bn, while ordinary income declined 25.9% to $136m.
