Actually my first eroge. I learned so much about how computer files worked by trying to patch this damned game on Steam so many years back. Even then it would have wierd glitches like one route having a pop-up image of a book stuck on screen for at least 70% of the route, and the duck in a majority of another. Nearly bricked the old family PC trying (incorrectly) to switch to Japanese Locale. I owe almost all my computer knowledge thanks to this one damned game, and I'm thankful. Enjoy it, everyone.
