I did find an error while I was playing the demo. During the scene where you're talking to the Egon over noodles and he mentions how the place you came from is not the best place, when I stayed silent it gave an error. I wasn't sure where you'd like me to put any info like that when I noticed it, so here it is.
Other than that, the game is fabulous. I like the story depth and plot and the characters are interesting and I'm excited for the full thing.
