The game is fun. Im just not a fan of the lighting and gui design. very dull looking. Also it would be better if the camera was easier to move in battles just so you could see the whole picture. Unlike games like tower defense, it requires quick action and you want to see your troops battling others. It would be nice if you could switch from 2d to 3d movement of the camera.
Also, the battle goes too quickly. In 3 seconds, i had lost both of my towers without me even knowing.
Additionally, the pathfinding has a lot of bugs.
