Excellent game. well thought out characters and plot. Relatively realistic characters and setting for the genera. Easy to immerse with, none of that cringy otaku meets catgirl stuff. I don't know how many hours I've spent on this game over the years, but it's a LOT of hours.  Huge replay value. Very funny in a sexy way and insanely hot. Probably one of my top 3 adult games of all time.
