Excellence in simplicity
This is one HELL of a game for a first timer!! The graphics were good as well as the gunfire sounds and I feel the length was just about right too I actually jumped up out of my chair when the helicopters finally came! Truly a marvelous game that proves that it doesn't have to be complex to be fun
I have only a few minor suggestions there started to be a good amount of lag in the later levels and i found this mostly happened during the reload animation you could probably just take that out as most players eyes will be rooted to the steadily advancing line of cannibalistic zombies (which were btw really great looking as well) and i found the use of the chainsaw to be a bit glitchy (sometimes it would work and sometimes it wouldn't) and the shotguns were a bit under-powered considering how long they took to re-load (though my aim might have just sucked) and lastly maybe a music change or two thoughout the game to keep the atmosphere fresh and spooky (but i do realize there is the filesize to consider)
oh and try to get the surgeon general to put a warning on this thing as it is a highly addictive substance
thanks for such a great game and keep up the good work!!!
