Justin Rivera: The UI for this game is super clean, which I feel is very important for almost any game but especially true for mobile games. The screen space is limited, so being able to convey as much information as possible while not cluttering the screen and overloading the player is pretty impressive. It is also nice to see a well-polished 3D game in this genre, as most tower defense type games are typically 2D. It is a nice breath of fresh air
