AppAdvice: Fist Face Fight (Free) by Jared Bailey is a frantic physics-based combat arcade game that goes by the “just one more” mentality. If you’re in the mood to punch things with your fist, then this game may just be right up your alley.
148apps: Fist Face Fight is slow to get started and runs out of gas quickly, but it's an enjoyable ride until that point.
Touch Arcade: Away from the heart. You have to bounce the ninjas—no, punch them—away from the heart, not toward it. Indiscriminate punching isn't good enough. "Defend Heart!" they said. You had one job, and you failed by scoring on your own goal, punching some guy right into your own vulnerable heart. There might be a metaphor there.
Pocket Gamer: Throughout human existence there have been countless fist fights over matters of the heart. But none, we'd wager, quite like Fist Face Fight.
In this game, you control a creepily disembodied (disarmed?) fist, fighting off ninja hoards as they run towards an exposed heart.
