Note: I have never played Faith, but I am familiar with it.
I liked this game. I love creepy stuff, and the presentation was pretty good throughout. SAM voice was great, and the music was nice too. I also really liked how you had the titlecard sequence. The movement could've been smoother, but it felt kind of stylistically clunky. UI scaling I think is the game's greatest weakness.
The story was interesting enough. I thought I predicted the whole plot after the first scene, but you surprised me heheh.
Overall, I'd say it was pretty good.
