Wow… Looks like it’s been a while since you last visited us ;) We thoroughly test the transfer of saves between two or three versions, but unfortunately we don’t have the technical resources to go any deeper. However, we try to develop the game so that even the oldest saves are compatible, but sometimes this is simply not technically possible.
We are currently working on reworking the first hour of the game, so I hope you’ll enjoy diving back into the story!
