Thanks!
The game (as well as the name of 'Nevelspoock') is based on portrait-paintings from old photographs, which are painted from actual photo's from roughly 1850's-1920's. The paintings are by @marty-art, and together they make for a fictional and mysterious family. The object of the game is to explore the domain and discover the secrets of the family.
I'll be following your series, always nice to see historical games reviewed!
