AWESOME!!!
Fire-starts off strong, but is the least powerful when fully upgraded. It's the cheapest to upgrade, though.
plant-starts off the weakest, but is the strongest fully upgraded.(besides the flower one.)
water-kinda balanced. has awesome range.
storm-kicks ass in the beggining, but it can't be upgraded, so you can buy one in the first few turns, but no more.
flower-this thing is godly, but it takes so much money to upgrade it. I've only been able to upgrade it once or twice.
My score is 71, and my friend got 75(give or take a few, It's been a couple weeks.)
