i don't know if it's a build that's available right now, the linked gf mechanic was mostly removed and replaced with the asynchronous assists. assists are still an area i'm sort of tinkering with, though i like the asynchronous style currently. There were issues with the linked-jojo-stand style where some moves don't _work_ correctly from the gf position, functionally.
if you are interested in playing that build i can see about relisting it or reuploading it if it's been removed. i've done a lot of build updates so i prune the list from time to time to keep it readable. there are sometimes issues with save data jumping back in version number, though, so it may be a little tricky to load up if you don't know how to manage the save data.
