The game engine was always crap, let's be honest about it. It sucks big time: you can't have different saves, you can't skip content like you would in normal games, you can't take screenshots, the gallery sucks, the game mechanics are linear and boring, etc. Quite often unique doesn't mean better.
The best thing about this game was its dreamlike atmosphere and the gorgeous ladies. Besides, in the beginning it seemed like the story was headed to something really interesting.
I used to love this game, I had it in my signature for over 1 year. Now I don't care much about it, it's just a huge pile of nonsense accessible through an extremely inconvenient UI, adorned with mediocre and anticlimatic sex animations (instead of sexy still renders, which is all it would need).
The Halloween/Xmas special will be really exciting in February!
