There's only so much I can reveal in an hour of gameplay without it feeling too rushed ^^'. Jason's route might have ended up being one of the tamest routes we have planned, which imo makes sense to keep his content fairly "normal"; He's one of the most popular gateway slashers. On the opposite spectrum we have two whole ass demons; one that manipulates your dreams and another that takes you to a world of pain and suffering (and pleasure) They're not going to be for everyone.
(DEMO SPOILERS AHEAD) There are endings in the demo where Jason kills you (and there will be plenty more deaths ahead) so I hope that satisfies your needs for the time being!
