Thank you for this! This is really cool, and in some ways this feels like a kind of post-police game? I really like how the communities maintain their autonomy even in the midst of problems, and the harmonists are mostly there to support. It feels like a very rare thing, when the norm for most games is to swoop in and be the heroes and saviours.
You mentioned not having time to find people to review this -- the English seems almost perfect to me. The only thing I noticed: for some reason in English even when “they” is singular you use the plural form of the verb. So it should be “They describe” (not “They describes”) and “Where do they come from” (not “Where does they come from”) and “Why do they care so much” (not “Why does they care so much”).
Thank you again for sharing.
