Are you kidding me!?!  It's freaking Punch Out from the NES on your iPhone!  You punch by tapping where you want to hit and dodge by pressing the bottom buttons indicating which way you want to go.  I really liked this game mainly because I was addicted to Punch Out as a kid.  So I'm extremely happy to have found this.

If you don't know what Punch Out was you absolutely have to play this game.
