Pretty Good...
It was a very fun, interesting time killer but there are only two things that make this an 8/10.
1: That link that you put near the bottom for your website is very annoying. I have died and had to start ALL OVER just so that you can get some people to follow your link.
2: The melee weapons could use some more originality. They all just cut the person and make them fall over. I think that the axe could instead chop the clone's heads off. The chainsaw should rip them in half (al a Gears of War) and the bat could smash them and put a dent in their heads. Although, the Dulies were a blast.
8/10 for the Effort
