was fun but too easy, once you realize you can spam upgraded flak towers to 3-star almost any level. Liked the artwort, but the different towers aren´t balanced very well. Change flak to only hit flying and you are one step closer, but I would still not need any of the later towers.
Nice game, even after having played the other two this ist still pretty neat. Survival mode should be a little less repetitive, afer a while you only get one kind of plane and it gets pretty boring. I like the hardness of the last few levels though, I just think the endless mode should gain a few twists.
