Doing too much...stop.
Nintendo...this is a mobile game. Stop with all the frickin dialog boxes and tutorials. Only you could make a horizontal platformer complicated. You should not have to invest 45 minutes to get started with a mobile game.
The best mobile downloads require very little if any explanation and have plenty of "info" sections if you dont understand something. Use this approach instead of interrupting my game play to explain something I can already intuit.
