I actually loved playing this game, most fun I've had out of playing any of these games, one sad thing was that at a certain point I had a bunch of turrets and walls set up, and I was totally crushing it and then the enemies stopped spawning, and I'm not sure, maybe it was something I was supposed to do, but I couldn't play the game anymore and I was really sad cuz I was enjoying it :(. Also, it took me a little to figure out you could only place the turrets on the circle walls, so maybe making that more clear.
