Just finished playing, and *spoilers below*
Uh, besides that =P well done! I dig the art style; it has the feel of some older BL doujin games. The soundtrack is haunting and lovely, and really adds to the unsettling atmosphere of the cathedral.
When you said "Nitro+Chiral inspired" in the Kickstarter, I was prepared for something worse than bad end rape. That wasn't a disappointment for me (I'd say I tolerate darker content more than enjoy it), but might be for someone else.
Anyway, I really enjoyed the game! Looking forward to your future projects =)
*damn you for making me ship [certain characters in the redacted route] and then [redacted]
Sorry, my attempt at spoiler tags did not work =(
