Kung Fu Warrior is 69p or $0.99 in the Apple App Store for the iPhone, iPod Touch and iPad. It is a simple but very addictive game.
The gameplay consists of you surviving different waves of enemies that come from your left and right. There are on screen controls that let you go left and right, jump/block, normal attack and high power attack. The levels are designed well and you can see the action without anything getting in your way.
There are different types of enemies that all have different levels of health and weapons. There are move combinations that let you hit harder and do special moves.
The graphics look pretty awesome on my iPod Touch 4g and I would suggest this game to anyone because of its awesome gameplay and addictiveness.
