TAS tie! This took about three hours, AND I had to use these silly controls: D is right (of course) Spacebar is B numpad 0 is Jump numpad / is Left This allows me to do a simple one frame right release with two fingers as well as flicking left (/) and jump (0) almost simultaneously to get an easy R L R+A. Regular 19 accel was stupidly difficult to pull off though, so that held me back from both the tas accel at the start and FFA coming out of the pipe.

Note: GG man. I think you would be a good contender for warpless or any%.
