I wasn't given any instructions with this game, so I won't be able to waffle on about the plot and saving the world single handedly, as I am wont to do. But I'll tell you what you must do in the game instead. You play a knight in a suit of armour who runs rightwards along a castle, shooting animals and dodging arrows. Where the Kung Fu bit comes in is beyond me!
It looks quite good in the screenshot, doesn't it? Well, in practice it doesn't quite come off. I think that's because it is a little too difficult; the arrows are hard to dodge and hardly anything happens when you lose a life, so you don't notice until the game ends.
I cannot recommend this. It is unplayable and unaddictive.
