Kudos for tackling some heavy stuff and doing it well. That was a bleak one, in a different way to some of the others in the jam. I felt like there was a good degree of depth to the main 3 characters and their relationships; I definitely got the feeling that there's more to them than we've seen from this version of the game.
I think the uncertainty the main 3 characters feel around each other worked really well - there was a bit of tension in feeling empathy for the three of them, and seeing them pulling in different directions. I think you chose the right moments to show the player things outright, and the right moments to pull away and leave things to the imagination. The feeling of unreality in some sections worked well, and added to the feeling of foreboding.
From your response to Scream Catalogue below it sounds like you were unsure where you wanted the story to go - I hope you (or your characters!) figure that out. It'd be great to see a longer version if you decide to keep working on it. Well done!
