I had monsters and about 50 health, then the CPU playes a crimson dragon with 12 ATK, and I played 2 parralel universes and a chaos seed which happened to be another parallel universe so i got 3 dragons. yay!
I gotta good way to win. Make a formation of the cheapest towers like an "E" shape. The critters should just take the one which is a straight line cuz it's the shortest then when they are there, blobk the end and they will go all the way back up. You can just sell the tower and do the same thing next round. :)
