I really like this game and the other 2 kingdom rush games, i have played them more than any other game I have. Th only thing they could perhaps change, is how much the heroes cost, that you control their abilities( that you choose when and where to use them), make them stronger and more unique. Also change the heroes of the first game to make tham work like the heroes of the other 2 games, they stay at lvl 10 and you can choose what to upgrade. Keep up the great work and dont stop making expansions maybe make an other game in this style? I'd love it!
I hope you can apreciate it.
