As of today, the Beat the Game leaderboard uses time without loads. This change was made to ensure fairness among runners regardless of whether they play on PC or Switch (which has longer load times than the average PC) or in case they have a slower PC than other runners. The rules have been updated, please read them to be up-to-date.
The timing for IL runs has been changed to time without loads as well. This means you can now submit level PBs from full-game runs to the IL leaderboard.
Thanks and good luck!
