The human hand cannot be successfully simulated with 5 button. With no sign of intuitive controls this game is so hard to play. maybe you should do robot surgery with a robot arm and a way to switch tools on it?
I enjoyed this game, I thought it was overly simplistic at first but after playing for a while I actually found that I liked the upgrade system pretty well, the premium content doesn't bother me because you really dont need it to complete the game. some options to change how the troops ai works would be nice so that you arent constantly spreading out or having to micro manage individual units in a fast paced game but it still isn't a necessity to play the game. 4 stars, good time killer lacks unique game play.
