Description: Protect your gems from being stolen by “good” heroes in this tower defense game. Overlord, you have all the power of orcs, undead and demons.

Instructions: Use mouse (hold SHIFT to build multiple towers or cast multiple spells). The game has a bult-in tutorial. Try to annihilate the enemies before they grab a gem, but even if they do, you’ll have a chance to annihilate them on their way back and you’ll save the gem.
