This was intentional to trick the player with some perspective "issues". I didn't make the level personally but when I tried it I saw the path directly, so I would say it depends on how much you're used to figure out things in 3D or something. That said you're not the first one telling us that perspective trick bad hard to figure out, we will try to avoid those kind of levels in the future for sure (if there is any...future, whatsoever).
