I did a bit of a dif maze to win the 100 badge. I juggled but only had 2 exits , both near the bottom so I only had to move the mouse a bit to put other block in. Up near the top I had a block I could remove to make a short cut to regroup the mobs.
Had 1 bash tower and 9 flying towers. The 9 flying had 2 boost towers along with after level 77(if that is flying been over a month now since i did it) flys some freeze towers to slow down the next flying. after that flying I sold all my air attacks and pumped up as much ground attacks as I could to get to points I needed.
