I would consider myself a speedrunner, I speedrun Minecraft (although haven't submitted a run because I didn't record my only run!), as well as Karlson and some other random Roblox games from time to time though most of them have a timer built-in so this is my first time using livesplit. I don't know what's legal and what's not and I'm trying to submit my PB run but I don't know if the splits.io link is needed o_0

The splits .io link isn’t needed

its not needed at all

Splits.io is not needed for a speedrun submission.
