Casual tower defense game with great graphic and distinct units and heroes.
+Cute and nice graphic
+Distinct towers with upgrades
+Different advanced towers to choose
+Unique heroes to help defense
+Tech tree to further upgrade towers or skills
+Lots of map with different designs and challenges
-Short and ordinary story
-Too many skill points, lots of points left after all tech trees are fully upgraded
Nice and easy to play. Heroes and towers are quite balanced so that you still have things to do while towers are slashing enemies!
