Harmonia gave me a mixed feeling as I couldn’t decide whether or not it was a well-written story. The first half was a bit too slow while the later half made up for it. Personally, I think the writer tried a bit too hard to make Harmonia a heartwrenching story, hence, the narrative when developing the conflict between characters feels forced and unnatural. The ending left me unsatisfied with a “happy” closure without bothering to explain the process to achieve said “happy” closure other than “time will heal it all”
Nonetheless, Harmonia explored a rather interesting concept of human emotions and the legacy succession of civilization; it was a fun experience.

pretty good, pretty sad. If you haven't played it already, try out another VN on steam called "Lucy The Eternity She Wished For." It's korean instead of japanese, but contextually very similar.
