not true, feel free to submit your first completed run
to add to benchbotch's statement you can also make a customizable one cycle I recommend doing the obsidian one cycle. It's extremely easy to 5 bed with it.
@benchbotch no need to be toxic he stated above that he doesn't know what ssg is, chill out.
pearl datapack is what people are saying but you can see shell guy's vid on youtube
Yes you can
doesnt matter which ever one is easier for you
Give jellysquid mods a shot it might improve your fps, with all of them I get 150 fps on a potato laptop. If not, just hope they add the category or do runs privately for yourself. Hope this helps :D
use sethbling's data pack he has nether portal building as well as many other things that would help you on a speedrun.
this rule was implemented recently so runs previous to that were verified with Optifine but now expect them to be rejected if you use Optifine.
Read the rules before submitting a run.
