There is no true ending. Really. There is no secret, hidden dialogue (go check!), there is no moon berry, there is no crystal heart. Nothing.

What makes one "ending" different from the other? The fact that less people achieved one? The fact that one took much more time, much more energy? Who will even know which ending you got, unless you go out of your way to tell them?

Who is to say what the "true ending" is? Perhaps the true ending is to go all the way up to the flag, and navigate your way all the way back down again, and jump into the water. After all, there is no real difference doing things that way than any other way.

There are an almost limitless amount of endings possible. Pick the one which is the truest to you, and that will be the true ending. To me, my true ending is going up the mountain without using the water, and then finishing the level. The water is left untouched, that way.

If someone opens this map, they may feel obligated to at least try some of the climb. After all, if not a single person ever attempts a certain section of the map, then surely all my effort on that was to waste, right?

But why does one part matter over any other? Why would it ever matter if nobody clears this map? If my own true ending involves never using something which I intentionally placed, which I put effort into molding to my vision, which I wrote poems for, which I wrote paragraphs for, then why does it matter if someone else's true ending never uses any other part of this map?

Like I said, there is no true ending. Call your preferred path whatever you want.
