There may be potential spoilers on patch 9, or the game's ending.
I beat patch 9, and its a good update. But I noticed for some reason, upon beating the forest area, you get transported to the beginning of the game and have to redo it. (fixed bug) but then I had this idea. I think time warps are a part of the HN francise, so you triggered a time warp of some kind, and thats why you were transported to the beginning of the game. And then there were these photo's of burnt, and broken houses in the forest. What if your transported to the start of the game, but the guest messed up the town. The place is just destroyed, and you gotta figure out what happened.
Note, an update like this would take time. So if you consider it, I would suggest adding little things to keep people content. When the game released, and one small new feature was added every 1-2 weeks, I pretty content. So release small patches, while the big stuff is in Dev. (This suggestion was on the previous Discord server, which seems to be abandoned now. Which is the reason I migrated it here.)
