This is what a game should be.
Truly fantastic game you have made. This game is near perfection really, im not kidding around. Shooting baddies have never been so fun. Once you kill a zombie you just want to kill another one, this is very addicting. The gun shots are easy to the ears and the visuals are simple but also easy to the eyes. The blood really stands out in the white backround. The new opponent you get to fight is really cool because they don't get killed very easily. The upgrade system is ingenuis, it makes the player want to kill more effectively and a wanting to know what the other weapons do and the upgrades. Ah, the upgrades one of the best points of this game when you get a gun that doesn't hold up on the heat of battle they get upgraded into stronger versions (when you get enough kills ofcourse), I thought that was very cool. I wish there were some music but I guess thats what iTunes is for.The other minor problem is the keys where you pick your weapon (key 1, 2, 3 etc.) got a little bit annoying as I accidently pick something I don't need and waste some of the ammo of it but other than that this game is unbeleiveable. You can easily spend over an hour on this game killing, trying other stages and trying to get the high score.
Plus side:
+Wide variety of equiment
+Nice gun sounds
+Easy to play
+Upgrade system IS AWESOME!
+Visuals are easy to look at
+Blood stands out
+Fun to kill baddies
Minor problems:
- No music for those who don't have any music
- Weapon selection is a bit tricky
Suggestions
Maybe an option where you can choose where you want the weapon hotkeys at.
