Minecraft IRL (mobile app)

We need another minecraft earth, but different. Where, example, an app where you have task. Lets say you have to do a certain dance, or cartwheel, in Walmart, and get a charecter creator item. You have the app and the record system. You record the title of store, and task all in one. Publish it to the social part of the app, and have it reviewed by employees to get the item.
