At this point I'm pretty sure ol' Nerdook could release a game based around cleaning up dog droppings and it'd still be on my top 3 games of any given month. Although I would have been really interested to see Nerdook put something out the month Kingdom Rush was released and watched those two battle it out for the top spot. . . . . . . oh yeah and 5 stars, as if there was even a question.
This game is stupid addictive. It surely has room for improvement but as far as a initial offering goes consider me impressed. I would suggest that you give some in game bonus besides a higher score (5/10 additional starting gold per level seems fair) for advancing in levels. Also maybe add visual changes to the character as you buy upgrades to gear. 4/5 stars well done!
