Very pretty, but the fencing was sufficiently obtuse that I died a lot and lost track of the atmosphere. Also, I don't know what the hint for the lockbox is, although it's probably something to do with the teardrop symbol on the sun painting and the four dots on the melted armor - but the group portrait looked like a hint, and apparently wasn't? And I'm not sure whether the cube shield was a hint for that or the alchemy lab. The interface was too annoying to brute force, though.
And I didn't find a use for the heated blanket. I'm guessing you have four routes past the monster, and they are swordfighting, music, poisoned meat, and meat-plus-a-meal. Maybe swordfighting doesn't work? It seems a shame that only one obstacle has multiple intended solutions.
I also wonder if this had some influence on Nowhere Stars, or if it's merely convergent evolution/shared influence from Dark Souls. The less-obviously-doomed ending was still pretty weird for suggesting you need brighter light, though. And I'm really surprised that the bells can actually hold back the precession of the sun, rather than just shielding the locals from its influence to some degree.
Hm.
