Good job, need a lil' improvement I think..
All's been laid out quite well, especially your main menu. The graphics were superb, as your game being a "stick figure set." As for a little improvement towards your game to make it better, it'd be nice if you have some kind of a difficulty setting to challenge people's skills (which makes people motivated to do better and ADDICTED to your game). Also, as for your weapons, if you could add people's classical favorite, the bat, acid grenades to attack multiple enemies, and a chainsaw for close quarters combat would work. As for your graphics, I saw a very small thing there where when you use weapons (like guns) the bullet holes goes on the background, even when you're using grenades. It's like you only have to aim to the specific target to kill 'em. It would be better if the "realistic" environment was created, where you throw grenades and it rolls for a couple of seconds before explosion, or aiming specific parts of the body and decapitating them when using katana or other "cutting" melee weapons. Anyway, I had fun with this, and I would definitely want to see a better version of it. All my 5 was on this, but for the review, a 9. And try giving your game scripts a little more attention, just a little. Rock on!
