You'll get new version of pack, when you pay for it 2 dollars.
I paid for it, but it's missing files, as I have sprites but no animations other than the idle ones. I have the full tileset and item animations (I think) too. Even the old assets are missing animations and other assets.
a paid asset has a description. a complete list of contents is provided. a paid asset does not copy a free one. animations will be updated this year
