as some people have said it really needs a speed up button and a pause button. some different towers would be nice not just 2 slightly different versions of the same tower. apart from that i think you are on the right path.... keep it up
I like the idea of this game but needs major improvements like the amount of levels, making it harder as you get along, more upgrade (maybe earn money not unlock part after levels) and not to mention the fact you can do one level over and over to get all parts and the level timers continue from last time of that level
