A terrific, classic style point and click adventure game. It's very impressive that the writing, art, coding and game design were all the work of one person.

I think the story and setting are far more sophisticated than is usual for this type of indie game. The world of spiritualism in Edwardian England is fascinating and a rich setting for a game of this sort. The characters are are well drawn and each has their own strong personality. The puzzles are logical and generally satisfying. There's good use of humour too, with some great jokes and witty exchanges.

The graphics are very well drawn, and along with the sound and music help to create a very strong sense of setting and period. You get a good variety of locations to explore, and I like the references to the literature that obviously helped inspire the game. The story is well written and reaches to a satisfying climax.

If there were elements where I thought the game could be improved, I think I'd break these down into 3:

A) Puzzles - I think the puzzles were logical and fitted thematically well, but I would have liked a couple of harder or more complex puzzles mixed in. Because the game design is fairly streamlined, you never have more than a few objects in your inventory so the solution is usually quite easy to arrive at. The only points I got stuck were where I'd missed a hotspot (which I don't mind - it's important that the player explore all the locations thoroughly. In this case it was the photos in the pub). But I appreciate the focus of the game was the story, and puzzle difficulty is very subjective. 

B) On occasion the dialogue conversations went on a bit too long, I thought particularly towards the end of the game (sections with Beatrice and Arthur Conan Doyle). At points I felt myself getting impatient to be given control of the character again. Some of the expositional scenes could have been made more engaging with more concise dialogue or giving the player dialogue options in the conversation. In the final room, I was expecting a final puzzle to solve, but the scene plays out automatically which was slightly anticlimactic. 

C) I enjoyed the story, but I felt some parts such as the scarlet stone, the Scottish cult and the Lovecraftian aspects felt a bit at odds with the focus on spiritualism and hauntings.

I hope that feedback is somewhat useful. Overall I thought the game was a very impressive achievement, I'll definitely keep an eye out for future games.
