I had the opportunity to play the Godzilla Pro yesterday. Put about 5-6 games on it. Wow, the flow around all those loops is insane.
The shot through the center, coming out to the left side of the building and then being swung partially into that left orbit from that magnet is a really cool feature. What a neat magnet! Basically a magnet cylinder...that's so neat.

The loops and pathways that are in the center and close portion of the playfield are really cool. Theres some unexpected paths of the ball at times and it all seemed quite surprising at first, but pretty exciting!

I was not sure what to think about the game when I saw the streams (in the minority, I guess), but in person I really had a great time playing this pro model. Seemed as though there was a roving blue insert at the stand-ups panning across the playfield, I think that it brought about jet attacks? Not sure, but it was a cool light show when you would hit one while lit.
So, for me, as far as flow goes, I was really impressed. It's pretty early code right now, right? Like, 0.79 code? For early code, this is a pretty great game, and I can only imagine that this game will continue to improve as code develops...but again, for me at first pass, I really liked it!
