UI isn't really consistent with it self, it feels like they are from two different games. The concept is super interesting, but I wish there were more variety in the disasters as well as some kind of a cost/benefit for stopping them, letting them go or letting them get worse outside of the metric of population.
Graphics were very good and the music was great!
Also, it's annoying to have the omnipresent being pop up EVERY wave to say more than one thing, or just let you know a new wave is coming.
