I've goofed with this one before but never beaten it (I think). Played on Mode 1 and died a few times. Grabbed the grail and took it back to the yellow castle not realising that this was the goal of the game. And it just stops. Had to look up an FAQ to find out that I beat it.

Am planning on redoing in Mode 2, but I'll need pen and paper for that, the mazes seem harder to just barrel your way through especially with the green fhqwhgads on your tail. And that bat, what a jerk.
