I made a speedrun edition! It auto-detects whether you run any% or 100% and shows it at the end. I fixed a bug where if you go to a different area while in a vehicle, you would continue to travel with that vehicle.
You can find a non-speedrun version here with this bugfix. The other bug related to a crash when entering portals in the share link isn’t fixed in this non-speedrun release; however, the speedrun edition doesn’t save, so it doesn’t have this issue. The bug will probably be fixed soon by the MakeCode Team when the next update rolls out (likely a hotfix).
