Yes, the right-drag rotations are cool and I like the fact that the
model has the general shape and topology of hypercubes but I don’t see
the game as being in anything other than 3D. It could even be done in 2D
if it is made clear when two lines intersect or are just crossing each
other without interacting. I therefore imagine that any well-chosen
parameters that make all edges appear roughly similar in length and
easily distinguished from each other will work just fine. Maybe it could
be interesting to know that short edges take the same amount of time to
traverse than lines that look long, but again there needn’t be anything
"higher dimensional" about them. Color differences could always indicate
length or the lines could be bent into loops of appropriate length. I
would probably only consider this a higher dimensional version of
Packman if the men can move freely in D-2 hyper-paths.

Regarding the difficulty of making your little guy execute the turns
that you intend, it might be easier to let the user click on any of the
dots which then causes your guy to take the shortest path to that goal.
That would also give the player more of a chance to plan longer
sequences which I expect would be more fun than worrying about whether
his guy will make the intended turns.

Actually it’s rotation in the (depth, color) space. For example, if you right-drag on right, points behind the Pacman go violet, points before it go yellow, yellow points go from you in the screen and violet points go back to you. Up-drag does the same with red/blue pair.

All this means that this pass goes from your main 3D space in some another direction, and it will be difficult to turn in it in 3D. So it’s better to make "color" rotation that will move far end of the pass deeper, and then orient it along Z axis. At first it is very tricky, but I hope that with some training we’ll be able to understand all this 4D/5D turns and use them better.
