It's not a fair game. When you have two enemies to defeat once you hit one you still have them both hitting you and taking your energy away. I feel that maybe a suggestion of possibly stunning the one you hit instead of letting them both cause your energy loss. That makes the game almost impossible to advance in. Really not a fair game seems like they only way to progress is to spend real money. If this issue and the others I have read aren't fixed I'm definitely going to be uninstalling.
