5 minutes in and I hear the music from good ol' Morenatsu. Love that you put that in there.
Yes! These songs were composed by a japanese group named Sentive - back in 2016 when I was about to release my first demo, I had my doubts if it's such a good idea to use any of the tracks that were featured in (already) legendary Morenatsu. Today in 2020, I think these melodies actually helps to intensify that touch of nostalgia, especially if you consider that the core story of both games is nearly identical (spending time with an old friends).
