So this is a simple trick. The in-game timer is saved on contact with a bell. By exiting to the Main Menu and then Continuing, you will be restored at your last bell with your in-game time set back to the previously saved time.
This means you can redo a section of the run over (from the last bell) with no time penalty.
The rules don't mention this trick. I'm guessing this is not allowed though.
Side note: This trick makes it possible to do password storage glitch within a single run, without any in-game time lose.
Edit: Forgot to mention that dying and respawning at a bell does not count as hitting the bell, so the last save will not be affected. meaning exiting and continuing will still work.
That's technically a segmented run instead of a single segment, so no it wouldn't be allowed.
Due to new runs from new runners, a Yolo subcategory has been added to 100%, Extra Spicy any%, and Extra Spicy 100%. Yolo any% will remain as a separate category (as opposed to subcategory) for now since I'm unsure how to merge it without having to copy all runs by hand. Let me know what you think i
