Just played the new version, very nice addition to the weapons this drone tool, although it kinda makes less sense to show the circle around its influence since it can travel all around the map.
Also noticed (which might be there before but I did not notice before) a kinda sudden peak in difficulty in between waves, like when huge insects start to come after very normal waves in a 3 level difficulty contract (I had beaten them before so maybe I had not pick this one)
Another thing that got me confused, when you click to move a soldier, my understanding is that they cannot cross the road (maybe because its lava or something they cannot walk over idk) it would be nice to show that they cannot go across the road.
I am following for more updates =)
