Really chaotic. I was confused at what was going on at first. Once I got the hang of it, it was decently fun. The artillery bombardment was really loud. Fighting off viruses was cool with different names, liked a pseudo boss fight.
The UI was a bit confusing. The graphics were simple but still decent; perhaps maybe a more consistent color palette would have done it good.
Overall, it was pretty fun, once I got a hang of the gameplay.
