The game looks really good: incredible graphics, great audio and very cool gameplay. I loved the aiming mechanic and also the box kicking was really cool. However, there were a few bugs that kinda ruined the experience: both me and the zombies could walk through walls, and I believe it is for this reason that i could not "interact" with the final ship to take it, if that's what was supposed to happen. Also, when i walked through stairs, the screen would become black. Since it's made in a week tho, it's an impressive work! Great one!
