One more byte off!

Here's a crappy gif of the program in action.

Given there's 2 nops inside the program itself, I'm confidant this can be golfed by at least one more byte. I'm willing to offer a bounty for a smaller version.


### Old version:

    H;e;r;0Pld;P_1;l;;o;Q\;W\;$2@\

Source laid out:

        H ; e ;
       r ; 0 P l
      d ; P _ 1 ;
     l ; ; o ; Q \
      ; W \ ; $ 2
       @ \ . . .
        . . . .

Reuses the same tricks as [Martin Ender's answer](https://codegolf.stackexchange.com/a/57600/76162), i.e `Q2` printed is the comma, P0 is the space, `P1` is the bang, but manages to be 2 bytes shorter through clever mirroring to reuse several `;`s and the `o`.

### Explanation:

Here's a coloured Hexagony grid to show the non-branching path that the pointer takes:

[![30 byte path][2]][2]

The executing code, ignoring mirrors, is:
    
    H;e;l;;o;Q2;P0;W;d$;o;$2r;0Pl;Wd;P1;@

Filtering out the skipped instructions and the literals that are overwritten by other literals, we are left with:
    
    H;e;l;;o;Q2;P0;W;o;r;l;d;P1;@

Which simply prints "Hello, World!"

After a few attempts, I gave up on a size 3 Hexagony answer. You need a minimum of 12 instructions out of 19 reserved for string literals, along with three `;`s for printing and one `@` for ending the program. This leaves only 3 spaces for IP management and memory management, provided you find the optimal path that reuses both the `o` and the `l`. From all this, I'll rule that a size 3 answer is impossible, though I'll give a sizable bounty to anyone who proves me wrong.
