This is one of the less original tower defence games, and its too poorly executed to stand up in this game genre where there are lots of choices in games! If you intend to play for more than 20 minutes, be prepared to spend some real money to unlock more levels and weapons! You can earn them over time gathering crystals, but youd only be playing the first two levels for dozens of hours before you can unlock even just one thing.
