The art is simply amazing! I love how the parallax background adjusts when the mouse moves, and it is also satisfying to see work altogether when the slider is being used. Not to mention, the background also transitions gracefully. For me these aspects certainly adds up to the juice of the game!
The constant switching of sides is great, and I get to use most of the characters in different orders. My favorite characters to deploy are the Mage and Shaman that's for sure.
