this game really has gone down hill since I played it a few years ago. There did use to be a fast forward button. There was also something just above all the units that showed it had numbers for each wave and if you clicked it you could see what you were going to be up against and theirs weaknesses, strengths and if they had any special abilities. The speed was so much faster, each one would take like 5-20mins depending on the map. This 3hrs to complete 1 map is a joke.
