Description: Take a role of an evil overlord of orcs, undead and demons and protect you gems from being stolen by good heroes.
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.
Use mouse (hold SHIFT to build multiple towers or cast multiple spells). You can also use hotkeys (see built-in hints for buttons etc.)
The game has a bult-in tutorial.
