umm how to update the game? im just being cautious cus I dont want to lose my saved files
If you're using the Itch.io App just click update.
Otherwise on Windows/Linux just extract the new archive somewhere (don't overwrite an old one) and run. Saves are stoled elsewhere and will be safe.
On Mac/Android, just install the new file over the top of the old one and your saves will be safe.
