also - while i do understand how some of what is in the game really looks copied from kingdom rush, I do think there are two main differences for the better (notwithstanding the obvious money grabbing):
1. the kingdom mechanics of strnegtheining heroes and towersand pvp are all interesting additions which do add flavor to the game not existing in kingdom rush.
2. I think the levels here are more challenging than the ones in kingdom rush, minus the dune worms in kingdom ush which i thought were horrible :P
in the end, what I am trying to say is that while this game is copying stuff, it also did bring some of its own stuff as well, and those stuff are not so bad...
