I'm starting a dev commentary series on my youtube channel, and it it I will be discussing my plans for a sequel. I will be talking about the development process of this custom story, what inspired the various scares and ideas, as well as the storyline. I accept suggestions on what do put in a sequel which you can post either here or on the youtube channel. Also, unrelated, I've started doing my own Let's Plays on the channel so check those out if you're interested.
You can check out episode 1 of the commentary series here: Youtube.com
