no ability upgrade redo and difficultly spike to impossible on easy if someone choose easy it is because an EASY play through. very limited choice of building towers and graphics are ripped off star wars for basic click bait. 1.5 was generous in my opinion all in all this is very poor effort!!! you can do better switch the cones with anything a star or a square box would be good and you are using the most notable icon for any star wars game......an AT-ST the standard unit featured in almost every stars wars game and movie. if that is not click bait for a star wars fan I don't know what is....good advertising scheme though but still a bad game.
