I downloaded and played it, to be honest, I was happy when it went into windowed mode, since I have a widescreen monitor so everything stretched, lol...
Okay, so the first thing I noticed, was the framerate was... well, not TERRIBLE, but pretty bad, enough to make button presses tedious, pressing to shoot and it happening like a second later meant I had to shoot in advance, although the movement keys worked fine, but everything else was so incredibly laggy with the button presses, I never even got to see the baseball bat animation because everytime I pressed the button to attack, it did nothing o.O
Aside from that, it may just be my computer (I can't see why, since it's a supercomputerwtfhax0r), but something I did think looked cool, was the amount of zombies onscreen, it really impressed me once I saw ATLEAST 20 zombies walking towards me, and I'm stuck in a corner with a gun that doesn't shoot, it was... fun, lol.
