Super creepy. Love the striking black and white aesthetic. The minimalism serves the game well. Love the biblical/eschatological references.
I'm not 100% sure if I'm playing the game right though. I press the hand podium in the central corridor, Azrael appears and I run to the other room (I assumed this was the exit the instructions talked about but I'm not sure). In the other room there is another hand podium so I press that one and then another angel appears and I run to the other end to another similar room (am I safe?). There's another hand podium here to so I press that one as well and another angel appears. So I'm running back and forth between rooms, but I'm not sure whether I'm doing what you intended or not. It could be very well I'm stupid, but I thought I would let you know my experience.
Anyway, great job! It's a really creepy atmospheric game.
