I couldn't enjoy the game last time I played it though I kinda like it years ago (but never got a time to finish it).
I guess my preference / taste of gaming has changing over time.
I got the game on steam for Christmas so I wanted to play the most of it.
I only found one soft-lock moment. If you make the key drop from the door too soon then you'll remain locked out.. I think, I simply reset the game and did it right.
But now I'm on the last chapter and before entering the the dark room I saved just before entering and it began the climactic battle. I tried resetting but it either I insist to continue from the climax or, when I did manage to load my save, it was just black.
