I like the visual of the infection spreading! When playing this I can only think back to games like pandemic, or infectonator (the zombie flash game). I think the simulator aspect of this is very neat, but it would be cool if I knew what mutations were gonna do besides being shapes. If you were to extend this project, I'd revisit the assets, because I feel like it would go a far way in keeping engagement. I had tons of fun with this project though :) cheers!
