too cryptic for me so I've decided to throw in the towel for now, but if you go back the way you came in that screen and then return to the road the screen goes black and you can't do anything
totally valid! i did hide that one last secret really well. i did also hide it on this itch.io page, if that's any help heheh. also thanks for pointing out that bug! that had totally slipped under my radar!
