Okay, I just beat level 99. It then sent me back to level one, and I know for a fact it's meant to be level one all over again because there's only one spider and two webs.
Wow... I am NEVER picking up the controller for this title again. The least they could do is give you the usual NES treatment for never-ending games, where you get to see some sort of reuniting of the main characters or cleansing/exit of the land's baddies, then a plot point where someone's kidnapped, or the evil comes back, or at least SOME form of explanation as to why you will never be totally done and victorious. If I want to try a title that never lets me rest or feel like a winner, I'll put in The Legend Of Kage.
Yes, I lurk. It's what I do. Which is why I can never go back to Carl's Jr.
