On the whole, the game brings a lot of innovation to the tower defense genre, quite an accomplishment considering how crowded it already is. The new gameplay mechanics create a lot of strategic depth, and the game adds replay value by keeping track of your high score for each level, allowing you to go back and replay them for much higher scores once your wizard has leveled up and is more powerful. Each level also has a "gold frame" high score, and achieving it on many battles unlocks bonus maps to play on. If you're a tower defense fan, I foresee this game taking up a lot of your time in the very near future.
Havoc and corruption swarms through the land, and you are one of those few wizards who can put an end to it. Create and combine magic gems, put them into your towers and banish the monsters back to hell!
