Author's comments and explanations:
Imagine reencoding all the Kangaroo TASes and then getting a single frame improvement.


(Link to video)

I'll just reuse Alyosha's note from the previous submission.

To fall optimally through the level, you want the ball not to spawn.
In order to get the ball not to spawn at the start of a level, it should be bouncing at the end of the previous level.
By delaying pressing up at the end of level 1 by two frames, you can set the ball up correctly for the next two levels and not have any delays.

The improvement comes from starting the final level sooner (a whole frame... wow) the other levels you can also start there sooner but you'll fall into the issue of the ball and then your chances of finishing the level like this less likely.

(The improvement was done first on 2.2.1 before redoing it on 2.6.2 without issue)


Samsara: I'm an expert on... Kangaroos? I feel like I shouldn't have claimed this one directly after Princess Rescue.

Samsara: Yep, this certainly finishes the Atari 2600 video game "Kangaroo" one frame quicker than the previous run. I've verified that this actually is the case and isn't just a weird "ends input earlier but the game finishes later" thing, so I'm accepting this as an improvement to the published run. E. I'll give you the "xcellent work" when you save 12 more frames in something else.

fsvgm777: Processing.
