What I liked: The auto tower defense concept is super neat. The upgrades are well thought out and well executed.
What could Improve: The pacing is all over the place. Sometimes I have nothing to do but to wait for the resources to arrive so I can upgrade but other times I'm trying not to die by micro managing which things to target. It is also hard to tell sometimes on what upgrades you can buy since the ui icons are pretty small.
Additional Comments: I really liked the gameplay it could be turned into a nice idle game with some polishing. The thing it lacks right now, imo, as I said is pacing.
