A timeless classic.
Today it's maybe the 10th time I've played this game. And I'll probably play it again in the future.
Why? Because it's one of the best defense games on Newgrounds. And when I say defense, I mean the "stand your ground - upgrade your weapons - wreak havoc on the incoming hordes" genre. Even today, this game (and its sequels) still stands out.
Balanced difficulty, weapon shop (with related upgrades), upgrades for the house and other perks who indirectly damage the enemy, a lot of levels, and a hilarious setting. I hope the author still visits NG, so he can take a look at my big THANK YOU for giving us one of the greatest games in the NG database.
If you like the defense game genre, try this. It will be worth your time.
