This game is criminally unknown even in Japan. I first learned about it years ago and wish I had paid the high price to buy a copy then; now it sells for 10 times as much, and that's if you can even find a copy. It's the only game missing from my physical collection that I know I want.
I've tried a couple of times to get into it over the years, but the language barrier was always too high for me and broke immersion. Hopefully I and others can now give this game the attention that I think it deserves.
