That’s exactly how it ended for me the first time I played it. I also played it on easy the whole game, and when I got to the end I realized I really had no idea what I was doing. The problem isn’t the game, it’s you. You skated through the game and never learned how to actually fight. Play it again on a higher difficulty and learn how it’s supposed to be played. That’s what I did, and I realized how stupid I had played it the first time.
