It took two live streams, inventing new routes on 4:3 and 4:7, and collectively 10 hours bringing it in... But I broke the 2-minute barrier in World 4, Laser World!

I'm guessing the next significant WR in this segment will have to implement the mega jump I attempted and missed in 4:9. Getting that saves at least another second. I also see the possibility of refining this new 4:3 route to avoid the megajump and keep the speed for a sub-11. But I couldn't find a good path for it. Outside of those, its just down to shaving off tenths of seconds by slightly faster movement in the levels I left time on.
