I played through this whole game (and saw both instances of author notes) and enjoyed it a lot! The different 'routes' were fun on their own and had enough unique between them to stand out even if they deliberately shared a lot, but it was the overarching connection that really brought it all together in a satisfying way. Very cool and nice story!
I also really like the art by mossinasi! I really like all the characters have bones worked into their designs, on top of being nicely connected, it also just looks really stylish. I'm envious of the gravekeeper's fashion sense.
