Stand & Deliver

To progress on a three star basis you need to buy extra power via In Game Purchases. This is not how this should be. There is no encyclopedia of friends and foes so you only have the notes provided when a monster appears for the first time. No information on monsters when you tap on them in the action. No there is also no reset button to undo your power ups or your character so you can start again and use a different strategy or ratio of power ups .
