I've never updated a game from itch before, do I just need to download the new version or do I need to do more? will my save convert to the new one?
You have to download the lastest version
If you want to keep your saves you have to do other stuff.
I recommend you to just save over every slot in the new version and then copy the save folder from your oldest version and overwrite the
new. (wont work if you dont do the first part.)
Im working on a new save system to avoid having to do this, but this is the only way right now to transfer the files from a older version
