Bro, is there any tutorial about how to export saves from the old version to the new one? And also my laptop got factory reset and I lost all my saves unfortunately. I really don't wanna start it over. Can I download them from somewhere? I was at the end of version 0.23
Saves generally get transferred between versions automatically. That is, of course, as long as the PC/laptop isn't being fully reset. As for a tutorial, there are probably a few of those on YouTube.
There are no official saves to download that I can point you to, no. However, you could join the Discord and ask if someone there is willing to send you theirs if they still have the save files from 0.23 - I believe at least a couple people on there do keep older saves.
