Doll's Nest [released a demo recently](https://store.steampowered.com/app/1839430/Dolls_Nest/), and I'm enjoying playing it (but it's still rough.) I wanted to crack open it's save data just to play around with and what's better than a recently released demo? I haven't touched Unreal Engine at all so I think this might be a good learning experience.
