Yes, this is common but difficult to use it consistently since it is frame perfect. Sometimes you might accidently trigger bunny hopping when you didn't intend it. While this seems a bit tricky to do so, it inevitably is the last resort to further optimize your runs in individual levels. I also used it in some of the levels.

Well done and interesting shortcut! I wonder if this can be done faster.

You applied them so quickly...

Those bold moves... it's really satisfying to see done in a row. Oh, in case you didn't know there's also two more shortcuts you can use in Black Level. One is non-glitched and the other one is glitched.

non-glitched:

glitched:

I did use it in my cyan & magenta run, too, but smaller acceleration. If we're really going to prohibit it or separte runs with this tenique, that means my cyan & magenta run should be glitched, too.

An amazing run with an incredible shortcut! But since you didn't use chatbox or menu to avoid being respawned, this is technically a glichless run. Please change the title of the video.

I've opened a support ticket of platform request for PICO 4 about 6 months ago, and yeah, still pending.

edit: PICO 4 was available some time ago, I didn't know that.
