This game seriously had peak sound design. Clicking buttons is a very satisfying sound, I hold the OST as the gold standard for fantasy music, everything...
I'd visited the original place of rampart houses: Shirakawa-go. The game made it perfectly in 25 years ago, when I was walking between those houses, my heart was always playing this track. I've stayed 2 days, 1st day is sunny, but 2nd day is cloudy -> rainy; the rain, made the mountains around Shirakawa-go, looked like the mountain background in the game.
