Just in case anyone else wants to transfer their saves to another machine or back them up in the cloud or whatever, and isn't a huge dork like me who immediately thought "ah I will use process monitor to check where the exe is reading/writing the saves from," the itch.io build stores your saved games in "C:\Users\[username]\AppData\LocalLow\GeographyOfRobots\norco\SaveData".
I actually had a very weird experience migrating from the GOG version a friend shared with me to the itch version I paid for to support the devs after it hooked me, because the GOG build stores the save files in just "C:\Users\[username]\AppData\LocalLow\GeographyOfRobots\norco" with no subdirectory. Very strange that that's different.
