It probably is. I'm playing it on a potato (Intel HD4000), but that's all that I have at the moment.
Sure:
No, tried it again, nothing happens: after the intro I go to the fuse box, activate it once (only one click), go back and the screen is still dark. Is there any way to get logging/debug information?
I wish my PC wasn't a potato (almost literally), but nevertheless, it was a great adventure and gave me an anxiety (in a good sense).
The switch does nothing except for the clicking sound. No matter how many time I press it, the computer doesn't turn on.
Have you ever seen any game/movie/etc about a lighthouse that isn't creepy?
Nevertheless, I enjoyed the game. Feel very nostalgic about my PS1 childhood. Also, I should play it during the night, but the moment is gone.
