Crashing

Let me start off by saying this game is by far better than the original...when it isnt crashing. It seems like I cant play for longer than 5 mins without it crashing and it always seems to be in the middle of a boss battle. To make matters worse after I reload it, Ive lost the energy points from that battle like I forfeited it. Im constantly have to either sit and wait while I rebuild energy or use my gold to refill it. Its very frustrating to get charged for 3 battles but only getting to actually get through 1. Please fix these bugs or Ill be deleting this game just off principle...
