Super Mario Run 2.0 promises new features and additional characters

UPDATE: Super Mario Run is now available to download on Android. It requires Android 4.2+ so be sure to have that version to play Mario on your phone!
Recently, Nintendo have announced that Super Mario Run is coming to Android devices March 23, 2017. They have also noted that a big update for the mobile game is on its way too. By updating to version 2.0, players will have access to new features which will hopefully revitalise gameplay for fans who have rinsed the title and looking for something new. The game will be getting additional characters along with more playable levels for the free version.
We don’t know when this update will officially come out, but hopefully when Android users receive it.
