BaconOmelette found this bug that allows continuous jumping in mid air and we have been testing it out. This lua script will test for when it is possible to continually jump in mid air. It seems to occur when you go onto an elevator or when Joe Musashi somehow ends up being pushed down inside a moving platform. Then jumping and attacking is possible in a loop among other actions like running.
If someone else wants tackle this to find improvements to the current routes or alternative spots to activate this go ahead. You could join us in the Shinobi discord linked below if you wish.
The current tas features several spots where this state is active. with the script running it should be obvious in the section with the sludge area in the BioWeapon level in particular. Shorter example on the long elevator section in 2-1.
