The game would be more fun if it didnt constantly crash in VS battles causing you to automatically "lose" the battle (losing rank and stamina). I wouldnt waste ANY money on in app purchases as its likely you will lose your money because of the crashes. Its apparent the company that owns this game doesnt have a very thorough QA before sending the game to general release. If it continues to crash, Ill delete the app and never look back.
