When you start a new save file you have to beat every minigame in each area to unlock the Mayor's "test" at the end of the area. That test consists of several minigames you have already done and you need to beat them all in a row without failing one to pass the test and advance to the next area.

In this run however, the test at the end of the second area just didn't happen. I could just go the last area immediately. I have no idea how or why this skip happened and I'm not sure I consider this a new WR.

Maybe I'll make a separate category for this but I'm not sure it makes sense before we figure out how this skip works.

There are timestamps in the video description to skip to the start of the run and to the moment when the skip happens.
