The first time I tried to play it, one of the doors was already open, so I ended up being able to go everywhere before encountering the goblin. None of it made any sense to me. On a second attempt, it worked normally. I'm still stuck though, as even with the map of the maze, there doesn't seem to be any way to progress. I'm following the path as outlined and on what I think is the last screen, nothing happens other than ending up at an earlier screen, regardless of the exit I take.
