Really interesting idea actually, I would have never thought about having towers that you can move around like this. I was put off by the hand drawn buttons but the concept is pretty good. I did find a bug with this though. One of my turrets broke and stopped shooting, I also couldn't move it anymore. I think it happened on the start of a new wave. Another of my turrets, in the same session, was taking up 3 lanes at once, making it impossible for me to attack certain enemies.
