I would give this a 95/100. The only reason that the 5 is gone is because of the LAG. What I was thinking when I saw the lag: hey lag get off this computer screen or I WILL KILL YOU!!!!!
The reason why this game lags so much is because how much action and detail the creator put in this game. Interesting tip: Did you know that on LEFT FOR DEAD the creator put zombies in the way to either: guard supplies, guard special zombies, block the ending. (next chapter)
Well if it makes you happy, here's another! Have an awesome day, rororo! :D
