In-game timer shows 39.37, but that timer is pretty inaccurate. Trying to time it myself showed about 39 seconds + 44 frames, or about 39.7333 seconds.

Shout-out to Parqer and Tomatomato for finding the main grapple strats.

Mod Comment: Retimed using vidtimer. Starts at: 08:12 and ends at: 47:45 for a time of 39.55
