This run is decent in my opinion. I'm not very attached to it since I basically just used Asumeh's previous TAS as a guideline for how to beat all the levels, with a few of my own optimizations. It did teach me a lot about the game, however, with all the lesser-known glitches that are required. My run has since been improved by Asumeh and Zejoant by about 6.3 seconds.
