And no in-app purchases. Yay!
As others have said, the graphics and gameplay are top-notch.
Only two critiques… First, the music is a 30-second or so loop that repeats endlessly, and could use some variation.
Second, the end boss is MUCH harder in iOS than the Flash version of the game. And the end boss is very dependent on luck. If his head does not pop up in the right places to allow you to get to him in a fraction of a second, you will not beat him fast enough and be forced to play the tedious parts of the tower for another try. Need to fix his difficulty or randomness.
Otherwise, great game.
