5 stars: This game has that perfect balances between free to play and pay content. You can play through the entire campaign on normal without spending anymore. You can pay for content to compete in other modes or complete higher difficulties. This game is a well down tower defense, good balance between different tower types. This is how a free to play tower game should be done!
4 stars: Good game but be prepared to watch a lot of ads and replay the same levels over and over again, unless you are prepared to pay for gold to upgrade
5 stars: So far the game is pretty cool. The balance of the game play and add's are perfect. Upgrading the unit's with the gold you're getting are reasonable and the game has its different difficultie level's.
5 stars: Good game. I haven't had to purchase anything to progress in the game. I would recommend this game to anyone whom enjoys tower defense games.
5 stars: Great take on the TD genre.The ability to move heroes around is a big bonus.Ads not intrusive and so far no pressure to pay.All good !!
5 stars: Great game layout, hero planes are great idea, very stable, ads are not annoying and good for bonuses.
5 stars: Great tower defense game all around hopefully there isn't like a max max or something at least new always happing like weapon wise
3 stars: Like always. Reach level 20 and nearly imposible to win. Pay like always is the only way.
5 stars: Fun Tower Defense with some additional elements, but not too many...
