Level 19.3 was aggravating. 95% was my usual score even when the screen looked cleared. I tried to repeat the steps that gave me 99% but each time netted a different result.
As you can guess, I spent much time trying to figure it out. What I missed was the obvious. Don’t clear everything with the birds.
On the successful attempt the sardine can landed on an uncleared ledge. The eagle soared in from the upper left corner and out through the lower right. It’d be my opinion it cleared debris that was off screen.
Anyway, I’m taking time to savor my success. I’m 100% happy for me.
