found a faster way oob ( Elevator ) and a way to clip through the Invisible Barrier ( saving roughly 30 - 40s ). the run is decent but certainly not perfect, i reckon there are about 5s or more here and there that you can still save with better execution. but grinding this level is really painful due to it being a huge cutscene fest, so i cba ( seriously more than 3 minutes of cutscenes on this one. lol )
