Its a good TD game, originally was looking for a Co-op TD to burn some hours on, but the gameplay is engaging unique for each character. Initially I did have a hard time navigating and understanding what I was suppose to be doing. The starting character does a good job at explaining the basics of gathering and spending recourse.

I have played in Solo/Duo/Trio and Quads and have had a great experience in them all. A lot of the reviews I've seen complain at the "complexity" of the IN GAME map design. I guess it would be if you never played anything requiring you to be challenged and make use of some form of thought. But all the maps I've experienced add a great gimmick that makes each map unique. Why would I want to use the same strategy every time?

My only complaint with the characters is the lack of towers, 4 is a good way to form the identity of each unit but feels like more can be added to create real synergy within itself.

I will agree although, the UI/UX is horrible. I would prefer a menu with map select compared to the navigation in the overworld.
