Everything about this game is fantastic; thought with greatness comes flaws. The only constructive critique have about this game is the resources gained per victory via level. Every round won is 50 resources of such item. Victory over the medium cities could be "75 Resources gained" and the hard cities could be "100 Resources gained". Giving players 50 Resources eery single match gives them a false hope. Players want more rewards as the difficulty increases. I'm taking a Fundamentals of Game Design class in college, so it is easier for me to understand the wants of gamers.
Nice tosee they finally added Achievements for this hgame. For all those who are annoyed of just holding down the fast forward button (if it works really well on your computer, because sometimes on others' computers it hardly works at all) go over the fast forward button and right click on it. It will stay on fast forward for as long as you dont click anyhting else. There really is no down side. IF anyhting, it just slows down again when you click out of it to build up your defense or upgrade your towers. click + to keep this for those who are annoyed of just holding the fast forward button down the whole time
