Very very slick. To get the best idea of the playfield and flow, look at the early art layout drawing overlaid on the blueprint. That mini-flipper seems redundant at first and blocks the bottom right flipper from making the same shots, until you can see how it's fed from the upper left flipper to pound away at those DRIFT targets. Six distinct shots on a single level is not to be sniffed at either. No drops, but on this style of game you'll hardly miss them.

The only criticisms I'd have of the layout are the obvious SDTM potential from between the pops, and that all the flippers have a feed to them except the bottom right. There's no inner orbit or return loop pass from the bottom left to the bottom right, and unless that mini-loop is also a ball lock it's also going to be the least important flipper in the game. You'd be spending more time trying to keep or pass the ball to the left.

Was that just player feedback, or did it include spectators? My personal opinion looking at the videos is there needs to be more communication with the player through callouts, and more acknowledgement of what the player is doing via screen displays. I can see a whole game being played and not be sure what progress has been made, and that makes it pretty dull to watch. I assume this can be put down to early code, and that it will be addressed.

Another suggestion, if it's not too late to alter the playfield print file: put more text on the game around the insert groups as to what the completed features actually do, and what lights and advances what.

I'm not fond of so many lights flashing in unison so much of the time either, you don't get a sense of hierarchy about what's most important to shoot for when a game does that.

I was able to figure the race rules out watching the videos again, but this is where lamp hierarchy is important. You also have those eight simple objectives for the triangular insert fan, which is a good way of doing it as it ties in everything on the playfield and gives them each a purpose. But since they can be done in any order, don't have everything flash at once; save that for things that have the priority to advance the races, or for when you're down to the latest couple of objectives left to make. A lit target should mean 'hit this', whereas a flashing one should mean 'hit this now'.

That's definitely an improvement to follow.

PETG, something like 5 or 6mm thick? New Canasta from a number of years back did the same.
