I see. That's nice! Still, finding all fossils, visiting all shops and talking to all villagers tends to take nearly an hour for me normally! But admittedly, I also do a lot of stuff in between; watering wilting flowers and shooting down balloons should I encounter any.
You can also use PWPs to block villager houses from being placed anywhere you don't want them! At the moment I'm also using a couple yellow benches to ward off houses from an area where I want to place other PWPs later... like the wisteria trellis that hasn't been suggested yet.
On another note, it's been over a week, so time for a new topic!
Do you have a particular goal or image you want to achieve in your village? If yes, what is it?
In my case, I lack creativity, so I usually end up trying to imitate something I like. I also recently kidnapped my brother's abandoned game card, so now I have two towns to govern! One of my towns is already being modeled after Mossdeep City (ORAS style), although I haven't really made much progress landscaping-wise, and the other town will be an autumn-season town slightly inspired by Hoogland, a town in the final Professor Layton game ( ´ ▽ ` )ゞ
