I think what Super Mario Run could improve on in the future, is cut the price in half. (4.99 would be perfect for this game.) have two extra worlds (Because 8 worlds in Mario is tradition.) have a offline mode containing just the main mode and none of the other stuff. Expand on the kingdom builder a bit more. (It's too simple right now.) Maybe have more playable characters in future updates or as MyNintendo rewards. (Hey if Peach, Toadette and Yoshi can be playable characters, Why not Wario, Daisy or Rosalina.) that's all i could think of at the moment.
