Inspired by the rolling technique of top-level Tetris players, I adjusted the grip to suit my needs for mashing B at the start of each level. The in-game timer was 0.1 or 0.2 higher on each level as a result of my efforts.

Also, I actually read the TAS notes properly and went full neutral before crossing the finish line to save one frame in each round.

Long Live Tiki Man!

Edit: I frame-counted it again, remembering to change the video quality to "Source", and it appears to be one frame faster!
