Best Tower Defense game ever and you never run out of new maps! This game is easy to learn. You can get a Gold medal with a little work, unless you play in Elite mode then good luck :-). One thing I like about the game is that if you make a mistake you can just hit the back button instead of having to start over. Some of the players have learned how to make maps that the game developer (Hidden Path) supports. You download the maps into your computer and somehow the game finds them. It is September 2020 and we still get 3-4 new maps a month. The new maps are even better then the originals. More sophisticated and cool effects. I'm not a map maker - just a map player.
