Thanks a lot for the feedback, really glad you liked it! Certain stats like genetic diversity are mostly arbitrary in their actual quantification, but we did implement a tooltip system to try and elaborate on some of the stats' implications if you hover over the name of the stat or upgrade button, but we probably should have made mention of it more explicit.
Totally agree about the notification log, but unfortunately we ran out of time by the time I thought of or could implement it. Thanks again for playing!
