I accidentially walked into the hedge on my way back out of the maze and then discovered there's a second secret passage: Has that always been a thing? I tried to find more but couldn't, just that one and the one by the sign. Also: There's an invisible box or something right where my farmer's looking. You can't walk on that spot. What's the deal with that? Just a bug where whatever is usually in that location is blocking you?
I've never tried it, so not sure if that's always been there. The invisible box I'm guessing is a way to help the player figure out how to go through the secret passage, kind of to force them up a few spaces so they go through the right way.
I've been in it, before. I agree, it feels like a giant winking eye telling you what to look for. ...well, not a literal winking eye. Though that would have a certain Salvador Dali-like feel. Especially if Leah contributed a sculpture of a melting timepiece.
