You are a knight, a curse knight... You wake up in the desert, hungover, unable to remember what happened to you (obliviously). You find the an old Scottish owl, the guardian of the Holy Grail, just lying there next to your smelly bulk! He's got a foul mouth on him and tells you that you need to drink to stay alive and get special powers.
You'll need to escape the desert and find your way out of the Great Pyramid, make friends with different people and creatures to help you along the way, walk through a sexy-parrot-infested jungle, hire a skeleton pirate to get you across the sea (guess how that turns out), visit the underwater world of the sirens (of course), save a bunch of kids from fanatical priests, and so on.
Gameplay is a "pee-zle" platformer with a rich story-driven humoristic conversation system. You've never played a game like this... And if you did, you're too drunk to remember anyway...
