Best demo I've played so far. Absolute loved this game and will follow after this review. Overall I think the game is very close to perfect, The only criticism I have is the running animations for the zombie are a bit stiff and need a more lively run. Plus some things that I think should stay are. One, keep the ammo counter only for the ammo in the gun, and not for the ammo stored in your inventory. Two, keep the horde-like nature of the zombies, as it's really scary watching the horde of zombies running toward you while shooting waiting for your ammo to go down.  I saw a comment criticizing this and in my opinion, it's more of a positive. Overall great game.
