Sweetness.
I'm not done playing, just taking a reveiw break, since I finally died(at level 17 ^_^). Amazing work, but I do sort of wish that some of the upgrades carried over between levels, rather than having to upgrade ever level. The overlord was kinda tough, took me two arch angels and 40+ troops to kill him.But, thankfully, you made him move slowly, so I beat him before he got to my castle. Fun annihilation, though. >:) Alright, back to the slaughter. Nice work!
