Oh wow that’s a long time XD you will be really surprised in how much has changed. There is a ton of story that’s been added since then. I will say though at 0.6.5 there was a major overhaul of the game that improved majority of the code and remastered a lot of renders along with new features. So since your save is from before that I would start a new save just to be safe but we also have saves in the discord server too 🙂 I hope you enjoy it!
