I ended up streaming this game yesterday while playing through a few of the Spooktober Game Jam games live, and I had a really, really wonderful time with this! Thank you for the lovely story. I only ended up playing through the true end due to time commitments, but the dynamic between A-Su and Xian-Xian really stuck with me, particularly the scene with lifting the veil and the descriptions of the river at the end, and I've recommended it directly to a few people who I thought would like it.
If you want to see my live reactions/see chat's nice comments, I've got the VOD up at https://www.twitch.tv/videos/2265021118 around 4:02:00. (If you do, I'm so sorry for my clumsy read-through, I'm mostly an art streamer and don't often do voice-overs for games.) Chat really loved Xian-Xian especially though!
