There's a lot going on here, thematically, despite the simplicity, and it's a novel concept (to me). I just got "stuck" in the narrative, and I can't tell if there's any way to progress or if it just keeps going.
Thanks for playing! There are technically four different endings, or at least outcomes, of which I should have been more clear. The most meaningful one is getting Eun to talk, although they are all very mechanically simple.
