Ooh, balance problem. Build a rank 2 archer and leave him be. He will attack from just inside your boss's range. If your boss gets the kill, the xp transfers to the campaign map. Go for as many rounds as you can before turning the archer in to a rank 4 RoF10 +10 damage monster and simply win, but with an extra level gained.
Balance is a little messed up. First fight, don't ever build troops. You'll finish with like 100 of everything. Buy a bunch of buildings and then play for real.
To those pointing out that you should do Defense or Puzzle missions to get over the hump at Target Time, those missions aren't unlocked yet. And you can't play old ones. So the game is stuck at an impossible tutorial level and the game gets a 2.
Minor in business law my butt. Just because someone else stole it first doesn't mean stealing gets around copyrighted images. And this isn't a parody at all, it's a game. And Blizzard makes games.
Awesome art style marred by total lack of game design. You can buy health between levels, but you get your three lives restored anyway. I have 2000 universal bullets and I have never once let go of the fire trigger. Bazooka just kills anything in one hit. First two bosses are the same. Lag from bazooka is pretty incredible. If you stand on one edge of the map nothing will spawn there so you can just shoot right. All levels and enemies are the same.
