Yesterday, my brother and I completed the game. You are able to get 3 endings. A bad one, a normal one, and a good one. We got the good one. If you want the good one, once you get to the temple of lightning, do not hit 14 lightning bolts. If you do you can not get the good ending. Even after completing the game it feels as if the story continues. But if you get the bad ending you have the opposite feeling.
