Something New

I beat all 3 kingdom rushes, and I found something out when I finished.
-The First one is too easy
-Most enemies are "unique" only in a way that they have super high defense or magic resistance
-The Towers are basically the same
-The tower choices are limited
-The only way to efficiently beat the very hard levels is to purchase heroes.
-The Heart-Giving item is missing on the Third one (is there a good reason for that?)
-This version hasnt been updated with new levels for a while. Is there a new one coming?
-The Bosses are too predictable

Please see this and probably make some changes to the game using these as a guideline.
