I think the first time you see credits, and it's still giving you options, if you keep going it'll lead you to all the other endings and eventually the true one In other words, there's only one "good" ending, and the only way to get to it is by going through all the "bad" ones, because it seems like some pathways don't unlock until you've explored other ones. tl;dr You've reached the credits? You're (probably) not done (unless you did everything right? idk). Keep going. Eventually you'll stop getting options. I personally think the experience as a whole is worth it.
