Dumbocalypse

Professor Brain was experimenting to create waves that increase brain power, but his experiments went horribly wrong (as always) and made everyone DUMB. Now they don't even know what to do in their daily lives. So, Professor Brain quickly created an app where people can post their questions and get replies from YOU. Don't look surprised; there is an app for literally anything these days. Your job is to reply to people as best as you can to maintain the balance of the planet. Just be cautious: don't overpopulate, don't make humans go extinct, don't make them too sad, and don't make them too happy. See how simple it is? Now, go and help those poor souls and don't forget to have fun!
