Enjoyable, however there are some balance issues. A little more information on the towers would help and anything but the colored balls would allow users a better chance to identify with the towers. The hero concept is unique and I enjoy that aspect. Keep up the good work (4/5)!
Had a lot of fun playing the game... never found it to be challenging at any point though. The addition of traps at certain locations might alter the game play a little bit. Great work!
