This game I have created when I was playing The curse of monkey island 3. It is about finding a map nad getting the big gem so you can rescue your girlfriend from being a solid gold statue. It almost doesn't have anything that goes near the original game, but it is fun :)
Legacy Player: The "Play online" link above uses the new Quest Viva WebPlayer, which is currently in Beta. In case of issues,
you can try the old WebPlayer.
