2 small and 1 not-so-small suggestions: 1. fix the sticky keys problem. 2. when u click off of the screen, make it pause. I lost a game that way. 3. Make a level editor. please. rate + if u liked any of these suggestions.
i completely agrees with jr637, all handies are not made equal. some should have different amount of gold drops. of course, this would raise tower prices too, so be prepared for that.
