there needs to be some indication of how each tower works prior to building them, or at least a sell function. i built an air tower which literally just shoots away from the path every time and i cant remove it. the game is alright but if im going to be honest i lost interest because there are so many other TDs out there that dont have these issues. there are definitely aspects of the game i think were well done too, we just need some better tool tips and a sell function
