I also want to complain and this is really something that drives me mad 
Honestly, winning the whole game in 2-3 months?
Several researches, building aircraft, vehicles and equipment and so on. At the same time the Pandorans evolve from crappy and weak melee warriors into heavy armoured threats and get reinforced by even heavier monsters in such a short time frame.
It feels too fast and it happens too much simultaneously …
I would like it when we would have more breaks, more time to breath. Let the research be take more time, manufacturing could be slower and also the Pandorans should have more time to get really strong.
But please, just for a better feeling, they should make anything somewhat slower and not too much at the same time.
