When making the second wizard tower, don't use the sheep upgrade unless you have a ton of ranged towers. If you have foot soldiers, they can't attack the running sheep unless you have barbarians throwing axes at them. Paladins can't hit them at all when they're sheep.
Concept ripoff of Xgen's motherload. But nevertheless, still a great game. Should have added more non-realistic ores and one stronger than diamond to make the game a bit more interesting.
