How do I climb? As far as I understand, after getting the feather, pressing the direction keys against the mountain and pressing "z". But I only climb a small bit and fall down, did also not manage to climb the climbing wall on the beach.

Then I saw in the store page movie that there can be more feathers. Does that mean the more feathers you have the higher you can climb?

Why is there now manual nowadays (or maybe I missed an ingame explanation?).

Would I miss much when I don't use soaring? For this you have to climb a mountain, then jump and press "z". If you miss the landing site, you have to climb the starting point again. And again. I know, the game is about patience and exploring, but I rather do this without overly repeating some dexterity tests.

Edit

Yes, it is explained - the more feathers, the higher you can climb and the guy at the visitor center tells you...

Still, manuals have the advantage that you can look up stuff whenever you need to.
