Feels like a Beta version
Great concept for a game but it feels unfinished and unpolished. Almost like and Alpha or Beta version.
The evolution points formula doesn't seem to make any sense. A virus or anything evolves as it multiplies, and as such the more people infected the more points you should have, except that's not how it works. It seems to be time based, such that as long as new people are infected, or dying every 3 ticks you get more points with diminishing returns as the game progresses. As such it makes sense to sell all symptoms and have the lowest visibility/infection spreadability as possible and just sit there to gain evo points.
The way the virus spreads is weird too, as it will pretty much never spread to another country unless its reached a critical number in a home country. As if 1 out of the 10,000 already infected is never someone who goes to another country.
Countries will continue to shut down airports, close boarders, switch to bottled water and so forth even when every person in the country is infected.
Countries will start closing boarders, airports, harbors, even when there is no visibility, no symptoms, and no lethality.
It's a good concept and could be a great game, but as it is its only okay.
