I love the manor a lot, and I've played Spirit House mode more than is probably healthy, just to get to see more of the inside of it. I may have attempted to draw a map. And while such attempts would be confidential, I can say that if they were made, they were unsuccessful.
I think I've mentioned this elsewhere, but I think the ghosts would have looked much better in a like environment. Compared with my real-life surroundings, it's glaringly obvious they're just animated, and you get things like Maya floating two inches above the coffee table, and the rest hovering somewhere in the distance when the wall is a foot away. It's meant to feel real, but it only draws attention to how not real it is.
Getting to explore at leisure was one of the things I really missed in Spirit Camera, to be honest. Even when you're in the manor you're either stuck in place or moving along steadily, with no chance to look around. I don't enjoy games where I feel like it's just a movie where my main job is pressing 'A' and beating a few battles and puzzles, and in Spirit Camera it's worse because there's literally no way to go off-track or make anything play out differently. Any sense of immersion or interactivity is completely superficial, because you can't even get lost, or miss a note, or ask Maya the wrong questions.
And just as a personal thing, I think being able to poke around someone's living space provides a context for an emotional attachment. Otherwise they're just cute scared girls being cute and scared, or cute stoical boys being... well, you get it. I loved getting to see Rei and Miku's house in FF3, and I like looking around the ghosts' houses in the rest, but in Spirit Camera you barely get that for any characters. You didn't get any of the cool little character details you could get by looking at things in the other games, and it made the plot feel even flimsier than it already was.
So uh, I think it's pretty obvious I have Feelings about this. I don't ask for stunningly well-developed characters or coherent plots or stellar gameplay, but let me look around the damn house.
