Game is poorly balanced and seems rushed out the door. Graphically, is on par with Kingdom Rush, but game play and progressions very poorly executed. As other reviewers have said, the game get impossibly hard suddenly, with no way to get past it. Would be better if your character get some experience even with a loss, so eventually you might the upgrades necessary to pass the level. At this state, you need almost perfect skill and perfect upgrades to pass.
Overall poor game and not up to the quality expected of this developer.
