As of 9 February 2023, this is sorely in need of an update for new strategies that save several seconds in a few levels. See the WR for a better route.

The following video has the best known routes for each level, as far as I'm currently aware.

My "sum of best" is currently 56.76 based on the level times in the video.

Of particular interest are levels 24, 26, 27, which each have tricky routes that each offer several seconds of time save. My current PB (and WR) of 1m12s310ms doesn't use them, but a future run could.

Update 9 February 2023: stage 27 is outdated. See the below video for the updated route:
