As fun as this game got later on, it was halted because of a severe bug in the game.
But first,
As stupid as the box art is its a fun game and I solely got it for the Original version as I loved it. BUT.....
At level 30 the game bugs out and there are even a few bugs before that.
Enemies die on their own or dissapear. But once you get to level 30 you CANNOT continue due to there being no boss to fight.

Things you can do that I did:
1. I bought my copy from gamecrazy, called them about the problem, they would have given me a refund had I not paid with a giftcard I had recieved. So they gave me to it as store credit.
I had to turn in a copy of the website mentioned above though.
If you bought this from a walmart or so I really wouldn't know what you would do as they do not take returns on ANY open game.
