Looking forward to seeing and getting more details, this sounds pretty cool and I love the BoB engine! :)
Well, this will hopefully make it even more exciting :D
And as a horror-themed BoB game, I immediately had to think of "Sleepaway", which you probably know as well. I can really recommend it or the podcast episodes on it on the One Shot network :)
So anyway, I'm really interested to see what you come up with and to try it out eventually!
