Wow, that was amazing. I haven't ever seen a cinematic/linear-type game like this before in a game jam. Obviously, fits very nicely with the theme.
Would have been nice to have some type of ambient sound in lieu of music, but nevertheless, the general feel of the game was still good without it.
The graphics are very nice; sets the mood well. I feel you made good use of shadows to avoid needing ample detail everywhere while also keeping things in the player's imagination.
The blood guessing game was a bit confusing. Perhaps, some sort of more intuitive indication of whether you got it right or wrong would make up for it, but I'm just speculating.
The voiceover was decent. The dialogue was written well. The very opening to the game, the whole sequence, felt very good and left me wondering if I clicked on the wrong game, lol.
Very cool submission.
