and I just want to say: the free flow map Idea is much, much older than desktop TD. it is an unoriginal game, but it bugs me that people are giving all the credit to dttd.
see: mafia wars, vamire wars, castle age, and almost all the other facebook and myspace games. you will look and see that only trolls and idiots whine about them there.
PEOPLE STOP WHINING ABOUT THE ENERGY BAR. It is there in many successful games, and all it means is that you either have to come back the next day, or pay for mist pots.
