Awesome Game
Really Fun shoot 'em up. It was a little easy, but that's not a bad thing in this situation. When you die, and start over you're returned to full health and your items are back to full (which is something I enjoy).
Although that being said there is no real negative to dying. In fact it is preferred since when you die everything is returned to you, all the zombies go away, and you're still at the same kill count. Even if you only made the kill counter go back to zero when you die then staying alive would become something to WANT/NEED.
What I would like to see in your next game
-A boss or multiple bosses sent a various intervals
-Obviously more of everything (Pets, Weapons, items, Maps)
-Negatives to dying (Loss of money, or Items)
-More difficulty (once you get a dog with a chaingun and a chaingun yourself its almost impossible to die(( Unless maybe you play till level 100 or something)))
Keep the invincible chainsaw action with Chaingun Dog. Mowing down that many zombies in a 5 seconds span is just pure fun times.
Oh BTW I just sat an jammed listening to the music.
All around good game. Just a little more stuff to play with, and a little harder to get to complete zombie destruction. Give us the things to draw out gameplay because I would really LOVE to play this game for more than 20- 30 minutes before geting bored :-D
