This is mainly a demonstration of new optimizations I have come across that I have not seen used yet, as there are still things I could have improved on. The grapple right after activating the switch to get out of the first room was a few frames slower than the using both grapples to leave, but it is possible to immediately latch onto the furthest grapple from standing by the switch; I have only done it once off camera and I have yet to replicate the angle, but it is possible. Also, Le Frog is annoying for me to fight, so I'd rather not keep trying to improve the time for the time being.

The other grapple optimizations are most definitely faster than what I have seen done previously. Room Two took a more direct route to the climbable wall (just hold hard left and wait one second before attempting to grapple) and used a grapple jump to skip the time climbing the wall. Room Three just skips the first grapple, which slightly faster. None of these optimizations are necessarily hard in terms of execution, so they're perfectly full-game run viable.
