good
I found the game very entertaining but have just a few complaints:
1- the aiming system only allowed for very limited range like if i wanted to shoot a barrel I would have to manoeuvre the character to a position where he could make the gun reach in that angle.
2- when you die you cant change your gun settings and try a new combination
3- the fast, crawling zombies were too resistant to bullets. Make them slower if their going to be that tough to kill.
But apart from these things it is a fantastic game. Keep up the good work!
