Just let me say, I love td Style games, especially the prequel to this one.
Swarm, however, is a little bit too frustrating for me.
Most of the levels feel like they were designed with only one solution, and any attempt to use a different method is simply doomed.
I play tower defense games for strategy. If I wanted to try and guess an exact method to win, I would go play codebreaker.
Allow a little more flexibility and this game would have 5 stars + a purchase for the full version.
