I was a long-time fan of this app. But the new long, multi-step interstitial ads between every single puzzle are toxic. I had to hit 3 different close buttons (that each had a delay before displaying) for one ad. And I can't even back out of the app once they start without accidentally clicking on them. It would be fine if the puzzles took longer than 30-60 seconds, but even the hardest puzzles are pretty quick (which I liked about this app). Now I'm watching ads more than I'm playing! Absurd.
