Moonstone!! I played so much of this on my Amiga as a kid. Me and my brother would play this for hours, just decapitating eachother over and over. We'd even settle bets over this game, instead of rock paper scissors!! I remember being scared by some of the monsters in this game, like the ones that would jump out of the mud and drag you down under. Probably messed me up as a kid, oh well!
