It's one of the stupidest and most confusing games I've personally ever played in the adult gaming scene and I've played a lot of different ones.
If you're already invested then it's probably worth a download but otherwise give it a miss. The porn is all static pictures mostly with the occasional GIF thrown in. The path of figuring out what to do next is impossible at times. There's dead ends that block off content and you can't repeat.
It's a nightmare.
The mod by spectreviper (which adds like 10 gb of content on top of the 7 gb base game) does a bit to help with the issue of dead ends and static images, but yea figuring out the path is difficult because of 2 reasons;
-The hints are vague
-English translation can be poor in areas, making things even more confusing
I would say, if you love a game near the size and scope of Big Kuyash and Son of a Bitch, this game is almost as big as those. It's far less straightforward however, so unless you use the walkthroughs provided in spectreviper's mod (which themselves are not 100% complete either) you will be wandering in the dark for hours.
