You should only need to download the new version, unzip it and run the .exe file. You do not need to move any saved files :D
We have not gotten our grades yet :P
Viewing post in What I've learned in the game and some small critiques
I swear if you don't get a freaking perfect grade, this random college student on the internet is going to be angry. Also I would really recommend documenting all the success the game has had just in case, as a way to say "Yeah, that B is nice, but the front page of this website, 100k+ downloads, and hundreds of youtubers playing this game say otherwise."
