I have an idea that i think this app can go far.
overall its a quiz app. where you play against friends, i feel this app can go really far if the right person makes it. if you are interested you must be a good developer, this app will be like temple run and scramble.
i feel it can go big as temple run.
also i feel it might cost a lot. but if the developer can join in with this. i think it can make really good money once its been hit on the app store.
