I could reveal something, something which many of you may know by now...

There is a timewarp to the medieval time, same tower, but older, with people living in it... Do a few quests for these guys, and you might find the key to the tower's roof, where the second ending begins. The timewarp will be a Bonuslevel Sign.

Note: You still get to battle Jazz, because he is in the top of the tower, not the tower roof. Only, on the roof... There is more...

If you battle Jazz without the key to the next level, you get another ending movie. Spaz will look a little sad, because he thinks he killed his own brother. He will go home, and you will end the episode by watching the credits...

And, NO, I won't reveal the second ending (With the key to the rooftop) so you will still have something to look forward to.
