Excellent prologue, there's a lot going on in the story and the pacing is very good too. It was engaging enough that I only noticed on my second playthrough, that there are no choices at all this early in the game. A small miracle, as I usually love choice-heavy stories :D
The art is nice, character art is kind of fun actually, and I love the characters' expressions. (I love how Parker's expressions differ little and change slowly, it really does make him unreadable and subtle. Love details like this!) All the characters that were introduced seem interesting too, and not just the LIs.
I'm really looking forward to the full game, the demo implies on so many interesting storylines to discover and the premise is very promising. And an independent and strong-willed female MC in regency era sound fun to play. Hope you will be able to continue IS sooner rather than later. Stay safe and healthy :)
