It's been quite a long time since I've played ADR so it good to get that feeling again. The pacing and presentation are all solid. One difference I noticed was the atmosphere of the game. You set up things to provide tension fairly early. ADR is more survival/mystery iirc, but in Beacon you could tell there were some threats looming.
I didn't expect the ending, reminds me of Steam demos where they pull out the cliffhanger to get you to wishlist the game. If you can continue carrying the story with those kinds of beats, you'll definitely stand out from some of the other similar games. Looking forward to seeing what twists you pull in the full version!
