Indiana Jones and the Infernal Machine - 05 "Palawan Lagoon" -
Shaved off 18 seconds from my old run, but unfortunately not without few annoying little time losses which costed around 4 secs.
New strats:
only noteworthy is the small ~5 sec timesave: you can move during a particular cutscene (found by the_kovic or House, idk). Rest is just better and more optimal movement.
