Hi Tingid, I’m glad you are enjoying the game so far. You’re question already got answered but I figured I’d repeat it just in case you wanted assurance from the dev. The game patches every Friday, unless I have some weird issue. In order to get the new version of the game just go to the game’s page and download the version you need. Once you have the new version you can delete the old one. Your save files are stored elsewhere on your computer so deleting the zip folder / extracted folder won’t effect them.
There is a patching system in place so you shouldn’t lose your save between patches. I do feel compelled to put an asterisk on this however. The game is in alpha at the moment and the patching system is likely not perfect. With V0.18 for instance we had a few questing issues. But bar any oddities your save data should remain intact between patches.
As far as support goes while I do like money, I currently have donations on itch disallowed. Maybe I’m old fashioned but I don’t really feel right taking money for a product this incomplete. Once the game reaches beta it will have a price tag associated with it, but until then my plan is to just keep it free.
