At the end of the final level is the big boss (I can't remember his name),
who is heavily armored and has a golden sword. In the background is a
jar. During the fight, the jar may flash-destroy it at that time, or you'll
have a long fight...
At the end, your hero(es) is/are standing proudly. Then the screen becomes
the opening story, with a few twists. The sword says "The end", and the
message is about your victory. Then come the credits, and at the end, you
go back to the title screen.
