Desert of Dusk finished. Saved 59 frames from the current movie at present. I get an before going to Area X-2 so I will get an EX skill of Reflect Laser. Reflect Laser is never used in exist TAS movies, but I found that it can save a little time.
A new route may be picked:
...Area X-2 -- Sunken library -- Energy Facility -- Gigantic Elevator -- Sub-Neo-Arcadia
I am not sure whether it save time.
