Another feature we’ve known about for a while is pole vaulting. It’s pretty simple on the surface: get a pole, find water, alley-oop, and there you go. Only… that’s what bridges are for. Whether pole vaulting is something that’s just for fun or that you (maybe everyone?) have to do until you can afford a bridge remains to be seen.
What would be interesting is if you can use it to get to places you couldn’t normally, like a hidden fruit oasis or something like that. Really, though, it looks fun enough to exist without some grander purpose. Plus, as the above image shows, HD water is confirmed.
