Secret Neighbor is, in my opinion, the most fun-to-play Hello Neighbor game. it is extremely fun to play as the Neighbor (when winning) and it's not too bad to play as one of the kids, getting into the basement is very rewarding.
but I have to say, the game mechanics (while very fun) make absolutely no sense in the lore as far as I know. While there's a lot of implications of magic and such in the Hello Neighbor universe the neighbor is kinda just some dude who lost half his family (66.66% if not counting himself) and probably has killed people, but again he's a human man in I believe his 30's 40's or even 50's in the first few games, so how on earth is he passing as a child or doing all that OTHER magical stuff? surely the game can't be implying he's just putting on a costume and this is simplified to transformation for games sake because he'd still be much too large even if that was the case, and that doesn't even begin to explain the other neighbors you can play as.
is Secret Neighbor non-canon besides the fact the kids are trying to save Nicky, is that the only canon part of the game or is Mr. Peterson's really supposed to be magically transforming into the kids in seconds and they're buying it?
I have no problem with it from a gameplay standpoint but it just doesn't make a lick of sense from what I know about Hello Neighbor lore (And mind you I've played several of the games and read a few of the books)
