Great game! Would give more stars

Ever since I got the game, I have been playing nonstop. This is a very addicting game that will make you think. My issues with the game is that there is only 12 levels, and I thought it was kinda easy once you unlocked the upgrades. I 3-starred all 12 levels with freeze, dragons, and cannons in a about an hour and a half.
