It's most likely just me, but it seems as if I can't find a way to reliably save my game. Will there be an option to copy exported data to clipboard, as well as import said data to access my save in the future?
There is no import into browsers due to some GX JS issues I wasn't able to solve. You can only import into desktop. It's unlikely I'll add clipboard soon, since I'm focusing on the full release for steam version, sorry. Strange that you can't reliably save, I'm guessing your browser's cache it at fault, deleting your data on its own.
