Hmmm It Has Potential But Needs Some Tweeks. Its Kind Of Hard To Tell If The Bullets Are Hitting Let Alone Damaging The Zombies, But That's Some Easy Fixes, Making The Bullet Just A Little Bigger Would Go A Long Way, And Either A Sound Effect When The Bullet Hits Them Or Hp Bars Over The Zombie's Heads So Players Can See That They Are In Fact Damaging Them. Only Other Major Note Would Be Have A Restart Button At The Game Over Screen.
