Nothing new from what I can tell. It's the standard jump and flutter in the E3 build that we've already seen.
Andy said a long time ago that the jungle environment in the Kickstarter was thrown in the bin -- completely discarded. How old is this gif and why is it only surfacing now? Does Team17 have an extremely outdated version of the game? I don't suppose Team17 are allowed to leak anything new without seeking permission first anyway. Maybe the gif is pulled from one of the various footage videos already released? I certainly can't remember every frame of every video.
