This three-tier layout is one of the most creative uses of ren py i've ever seen, though i havent seen much tbh. The audio and artstyle build a really stunning atmosphere.
Just that would already have been enough but the story is very interesting. I wasnt expecting deep themes like what are present obligations to past people and so on.
The sentence "judging past people by today's standards is like anthropomorphizing animals" will stay with me for a long time <3
