it says it has unlimited range but it doesnt attack the mobs.

I would be interested in seeing a "true" sandbox mode. The current sandbox does get rid of most of the obstacles, but I would love to have a mode where you could move around the Start and Ending grids, use all towers and where money would be infinite. I would like to try out certain strategies and try and see what setup could last the most rounds on the highest difficulty, without having to rely on the limitations and the randomness of the unlock system. Maybe also a system to change the type and amount ...
