Ooh, a non-Neuro game! Cool! And not just saying that because Snow.
The switch had me confused because I wasn't sure it worked, especially since it could be undone, maybe. But it's not too hard to check!
I wonder if it's possible to go the wrong direction from the start, but I guess that's why the target location is semi-visible after you've sorta lost sight of the start location? Good location design!
