This was... wow.
I have no words.
I absolutely loved this from beginning to end. H-Scenes were a bit weak but I really do not care - I love this to bits. Except the difficulty. Because holy fuck.
But yeah, please, for the love of god, if you do any additional content for this, please, please, for the love of god, let there be a happy ending for Lily and Pea. Because honestly, even if we go with the whole "I was dead when I boarded the train" (forgot what was said exactly but the gist is enough) thing, why not have her rediscover a sense of purpose in her life? She did the job, and not even a thank you, just the afterlife?
Death could at least be like "You know what, you did help immensely and did everything perfectly, have another go at life. If you get killed, though, it's over." Because I want a happy ending for the undead x undying pair, have them marry (or become... "roommates" (historians will call them friends), moving to the city). While I get that you were going for the theme and the way it is right now all fits the theme you chose, a happy ending could work as well. This isn't a FromSoftware game where everything sucks, for Christ's sake.
Please, at least consider it. The current ending had me bawling my eyes out and ruined my whole day. I beg on my knees.
The story was amazing, and the world was too. But again, the ending doesn't feel fair. I get that it's not about fairness, but please, still.
