Sooo much bugs.
Impossible to beat, and very buggy. Why did you submit it without the problems solved? You could have scored much higher. There are so much things that you need to fix.
1- You can't punch. Fix the punches!
2- Put more ammo. It's impossible to kill all of them with 12 bullets!
3- When i shot a zombie, he didn't die, but stopped, i mean he freezed suddenly!
4- Zombies do so much damage. Decrease the damage they make, or decrease the number of zombies, or add so much more healthpacks.
5- In the "you are dead" screen, when i click the cross, it jumps to the menu and the "you are dead" scrren again!
I gurantee, however, if you fix these, this game would rock!
