The Loop Trail
A short garden walk that doesn't add up. Every lap of the loop takes you into the next season, the cabin in the hillside is bigger inside than out, and its back door opens onto a mountaintop.
Three things here don't add up.
Walk the loop and watch what's past the stone threshold. Find the door in the hillside. Then find the cabin's back door.

How it works
It's a raycaster, the technique behind 1990s first-person games, with one change. The world is several separate grids, and some cell edges are portals: entering that cell in a given direction moves you, and every ray of sight, into another grid. The loop exists four times, once per season, joined end to start. The cabin's door leads into a room seven cells wide, even though the hill it's built into is one cell deep.
The same idea scales to the shared island: a place can grow without the map getting bigger, and memories could open doors into rooms only the people who left them have seen.
