Cool...
Very Addictive game...but, I agree with others in saying it gets a bit too hard too quickly...I mean, you can only upgrade the weapons 3 times....the mines become pretty much useless when the who screen is full of zombies...(meaning if you do lay a mine down you're only going to blow your character up along with a couple zombies if you're lucky.) So, If I may make a couple suggestions....Weapons need to have a higher effect or at least make it to where you can upgrade them a few more times than just 3 before they're Maxed out. And maybe make it to where you can also buy extra health or maybe buy something that lets your character take less damage as the levels get harder. Besides these few flaws, the game is very well made and I enjoyed playing it quite a bit.
