I like the idea of this and the story started great but I think I might have a bug of some kind? I couldn't really continue beyond the community hall. Maybe I didn't look hard enough but i couldn't find the key for the gate.
You can find the gate key in the room with the record player (walk in via the front doors, and it's the first door on the left), and it can be used to open the gate. It's on the side of the bookshelf, on the opposite side of the room from the ping-pong table. Best of luck!
