Is this made by Ironhide Studios or something? Huge amount of the interface looks identical to Kingdom Rush, especially when upgrading/completing levels; completely ripped off.
Found another bug - was on level 20 and when I finished the level the screen was fading out as usual but then all the sudden everything unfroze and the boss appeared. I was able to move for a few more seconds then I was prompted to the level complete screen. When trying to attempt level 21, I simply see "Enemies Left: NaN/NaN" and no monsters ever appear nor does the level ever end. Have tried over and over and still get the same issue, figure I'll be starting a new game to fix this issue.
Really irritating when you accidentally click your mouse while watching the castle and it pans back over to your catapult without the option of changing your view back to the castle.
