C:\Users\you\AppData\LocalLow\Full Frontal FrogI don't see an appdata folder when going into users at all.
Put that into File Explorer's address bar
Alternatively, type %appdata% into FE's address bar, and it will take you to the Roaming subfolder, and you should be able to go up one folder level by clicking either in the address bar where it says AppData, or by clicking the arrow pointing up next to the arrows for forward and back. Then you should see folders for Local, LocalLow, and Roaming. Click LocalLow and then find the folder called Full Frontal Frog, which if that one isn't there then you'll need to run the game at least once.
