Luckily, they're going to make "Arches" which will be the sequel. The teasers have been showing the gay couple Devon and Cameron (the coyote and bear) that show up at the end of some of the routes. There's also the prequel "The Smoke Room" that's come a decent way but far from over itself.
This game has also inspired me to start writing horror myself, and it's amazing to think how this game has inspired and affected so many people. It's no arguement that the team of EchoProject is very talented with what they do, and I can't wait to see what's in store for the future.
