It's an excellent game. I don't know any Japanese (read a little Kanji) and I have no problem playing it. I have PS version. Someone told me Saturn one is better (just like Snatcher, Saturn has big booklet), well, I don't really care. As long as I can play it, no big deal. The parts I have problem beating were bomb section and final shooting in the building. Kinda tough....
You can still get this game at NCS for $39. Grab it before it's too late.
