Way too easy

You can complete everything in this game in two days if you wanted to. One day if you really wanted to. Dont listen to the comment about needing to spend money, you can literally beat every level with 3 stars with one frost tower and massing the first tower with upgrades. Dont get me wrong, It killed some time, but theres no real depth to the game. You got small fast enemies, big slow enemies; towers that have long range, towers that have low range. And of course the all mighty frost tower. Thats about it
