im pretty glad to see the improvments of the pervious BD games
And there certainly are quite a bit of improvements! In the older three, at one point, I could name them all, but in BTD4, it would take weeks to memorize every new tower, bloon, and item. I'd say that BTD4 improved more from BTD3 than BTD3 improved from BTD1!
I can never remember my strategies for the BTD games until I play again, but what I do remember is that, for me, it gets impossible to play around the 300's in free play due to so much lag...
You make me think... I'll try again but I'm not sure about what proof I can give. My thoughts are a bit of a fluid picture so I might have given something from a previous game.
