I've gotten better at quickly charging spin dashes so I came back to see if I could sub 18 seconds. It was made a lot easier after I realized I could jump off of that ramp by the Past sign.

This was a painful run to get at times because there were THREE times where I beat the record but wasn't recording/didn't think it was good enough even though it was. However, this was my fastest time so maybe it was a good thing in the end.
