Yeah, I'm working on this again.
This is 7 frames faster than the WIP from 3 years ago. There are a couple changes but they're pretty small, and mostly serve to get Raph and the enemies into better positions.
My comment on the last WIP said there were variations that were very close together, but I've long forgotten what they actually were. There's a real possibility that I end up optimizing the current strats as much as I can and just move on. Hopefully that doesn't happen, but on the plus side it'd mean getting the TAS finished a year or two faster. :P
