Haven't been able to make this LAG. I've gotten very close, but I always get teleported OOB (https://imgur.com/Kj14LpX). Couldn't find any runs with keyboard inputs on display, so any help would be nice. Also if there are any discords I could join where I could ask questions like these, then that would also be appreciated.
Discord is linked on the sidebar on the left. Under Guides in the same sidebar, there also is a tutorial google doc linked, which has tutorials on pretty much every trick (including double lag with keyboard inputs), so checking those out should help you.
Starting today, runs that require video proof (top 25) and runs beyond that where video is the only form of proof, now require audio, as recording audio for only the game is now a native OBS feature.
