Wow, really funny idea! The art is also nice, but the gameplay is a little bit too simple and gets boring fast. Also, maybe add particles when the vaccine gets destroyed. And the music was waaayyyy too loud and overdriven, it hurt my ears a bit...but the sounds are great! This is a funny idea, with more evovled gameplay i could see this in the appstore soon! I hope my feedback helped you, it would be nice if you could check out our submission too. Thanks!
