So far so good. Though the layout is a bit confusing (and yet oddly nostalgic), the main dinning area is upstairs even though the kitchen is downstairs... with no evaluator in site. Now as I said I did used to go to a, building like this as a kid with one half of the building decided to play area and the other half to a seating/drinking one. Personally I would have the stage, seating/eating area, storage and the kitchen in the downstairs area. With the arcade, prize corner, Foxy's cove, reception and the Security office upstairs. As this is kinda similar to the building I used to go to, the play area and seating/drinking in one area with none related stuff in a different area. (It would also make the night guard's comment on how big the downstairs is make a more sense in my opinion as, you're greeted by a big empty room with Foxy's cove, some well used soft seats and the toilets on the othwe side of the room. With the massive play area around the corner.)
Obviously since this is all drawn and, unless you were going to rebuild the game again. It's completely illogical do rebuild the game's building layout (especially since all of that is just my opinion) though, one criticism I do have with layout is the hallway leading to the security office, it straight up looks like a wall from the staircase and not a hallway. Combine that with the movement boxes for going upstairs and to the hallway overlapping, I genuinely couldn't find the security office for longer than it needed to be.
I only have one gripe with the art direction and it's how Chica and Freddy look on Stage. As depth perception is a bit allover the place as they look to be a mile apart and look a too small on stage with, an oddly tall door behind them. It honestly looks like were it to open, you would unleashe hoards of hell upon the earth (which wouldn't be completely out of place in this franchise honestly). Making them bigger and not so far apart would better in my opinion (Foxy is a good example for how big they should be, granted we're closer to her but, she doesn't look tiny on her stage).
Apologies if I came off a bit strong as, I did genuinely enjoy my time playing this demo and can't wait to play future updates of this game.
