@Woutah - Purple belts are considered standard colors most places. It's all dependent on where you train. Where my wife used to train, purple was after orange, before red.
@ Schaleh -
Because you cannot grasp the incredible gains associated with the LHC and similar colliders does not make them any less astonishing for the scientific community. To call all of humanity "stupid" simply because you fail to comprehend something is irony at it's finest.
Well, I think I can officially say I give up after a full day of playing this fine little game. I've tried every tactic on the planet on that Cave-5, but the cloaked goblin blasts my castle every time. He jumps right over my entire army, completely avoiding the mermaid spells and a herd or other foes. I'd rate this game a lot higher if it weren't for Cave-5. That being said, 3/5. I dropped it down due to repetitive gameplay, frustratingly random card rewards, the blatant art theft from World of Warcraft, and a ridiculous "Final level."
