Really cool game! I didn't have a lot of issues with it, but I do have a couple things:
1) I do wish the game had sound. I think the player feedback visually was really good but I think good sound design could've elevated it a lot.
2) I also kind of wish that instead of your score being your percentage of infection, that you were allowed to get 100% infection regardless of time, and your score was the amount of days you took. Might just be a personal preference but I kind of wanted to see my run through but I got cut off after 72%.
I initially thought that this game would've been super confusing, but I actually didn't have a problem understanding what was going on. The animations (the bars going up , the territories getting greener), were also super satisfying and well done. Overall, it was genuinely a really good experience.
