I'm aware. My point is that a 20 star run that goes to the final bowser would allow BLJs and ban "jumping at a door" which is too arbitrary for a fullgame category.
There isn't an incredibly great reason to my knowledge, but banning 20 star door clip but not BLJs is so arbitrary considering the complexity of each respectively, that I figure it came about as a category extension just to practice overworld 1 more than anything.
Played on 1.3 but no option for submission yet.
You are correct, this route is actually not correct in that aspect (to my knowledge) and is overall quite outdated. I wouldn't recommend going off the world record to start though. I would recommend using this guide to learn all the stars on it, then picking and choosing which ones to use. Using the world record for Overworld 1 is a good idea though because it uses a fast and more consistent stage order.
