One of the best free tower defense games!

Currently at level 36 normal difficulty with base level 80 with 80hrs of game play and not a penny spent on in app purchase!! I really like the bonuses twice a day just for launching the app. Sometimes I get bonus items that really helps passing a level. I usually save up on resources by just playing the levels that I can pass without using any items at all. Then go all out when there are bonus items :) Still haven't touch the "hard" levels yet. Thank you for making such a fun game truly free!!
