That's an intentional bug, yar, but it's also bugged somewhat ironically. What's meant to happen is that you get a bit of the ways in to the next level while being stuck in the air, and then the system crashes (so long as you're not in the inverted parts of the program). If you were in a white space and were floating, that's an actual bug. If you were in a reddish space and were floating, that's an intended bug-feature.
Being stuck in the air in the negative worlds is how you'll access sub-worlds of that particular program as it won't be possible to jump in negative worlds once that program's logic is done.
Sorry about the GES menu being bugged; it's a side-effect of the new interaction system. There's some interplay going on where inputs are being fought over by the standard player controller, the player interaction script, and the interactionRegion which boots up the SNN menu in question presently that I've yet to completely sort out.
