I really enjoyed this game, the controls were decent up until around wave 35, and the game play and enemies were varied enough to keep me entertained. One of the only problems I have with it is that as far as I could tell there is no way to get rid of your buildings or soldiers once you have them unless they are destroyed by enemies. The problem with this is that once the waves get high, the lower grade buildings and soldiers clog up the forty soldier limit, thus limiting new buildings you make, which can kill you eventually because the lower soldiers cant keep up with the higher wave enemies. What I would like to see in an update is some way to get rid of them, maybe destroy them yourself with a button, or a way to sell them even to regain some money, and same with the soldiers produced by that building. Other then that great game, keep up the good work.
