Really beautiful artwork! This did not feel like a jam game, but a properly polished, fully-fledged game--and not only because of the polished feeling, but also due in no small part to the quality of writing.
I don't normally play a lot of visual novels, and don't have much experience with this genre, but this was really captivating. I must admit that I booted the game up while grabbing a bite, but ended up with an almost full plate when the game was done.
Because I just jumped in without reading much of the description, I initially expected a story like The Tell-Tale Heart. I have seen your mention of the The Fall of the House of Usher in the artistic inspirations section only after finishing the game, but the Gothic influence is unmistakable--which I really enjoy.
I decided to stick by Lord Ruysch, because it felt like a more fitting end to the story, one that complements the regrettable life they both have had.
Thanks a lot for the game, really nice work!
