The presentation on this game is excellent. The visuals were great and the music was also pretty nice.
Balance-wise, it felt really easy. It could've used some more mechanics that applied pressure or needed me to think more. It also felt like there wasn't much reason to make units, as the archer towers seemed to be good at pretty much everything on their own, and were pretty cheap. It would've been nice if we could see what each portal was currently making, and how long that'd take, because they felt really slow, and having that information available might've helped.
