Saw the stream and enjoyed it overall. A few things stood out, but not many, which I think shows it is pretty well thought out.
The 10,000,000 super jackpot is too high. 4-5 million would be a better balance.
With a ball sitting in the shooter lane in multiball waiting to be plunged, no scoop should kick out until the ball is plunged. The “plunge the ball” going on every 10 seconds while a lengthy single-ball multiball was happening wasn’t effective. Don’t give the ball back and the player will plunge the ball.
The “power up” portion of the scoop kickout is a little too long for how frequent it happens. The “thud” at the end is cool.
