Alright, I decided to play through Act 3. When I finally beat the Drunken
Master dude (does anyone who has the actual manual to this game know the
last boss' name), it showed all the bosses from the game as it usually does,
but instead of going on to Act 4, the words "Give Up!" appear on the screen.
If you press run the words disappear and then reappear. Keep pressing run
and you keep getting that message. I tried pressing the other buttons but
nothing can get you from this screen.
I find it hard to believe the game merely ends with that screen. There has
to be someone on this list who knows if this is the actual ending. Perhaps
it says something in the manual?
