It's a little bit simple, once you learn the game controls, it's not hard beating it every time. There's just not enough options to make it hard to master. I would really like to see this game developed though, spanning over several years instead of just one season.
The controls need some serious tweaking. The screen is fluttering all over the place, and it removes much of the skill portion of the game. Not really fun gunning for the gold medals when it's not how good you are, but how lucky you are with the screen movement that matters.
If I ever become a zombie, I'm going to opt for eating the random fried chicken, pizza or fish and chips lying in the street, instead of only trying to eat the guy shooting at me with a shotgun.
