Yeah, I’ve heard that from a few people.

I’m thinking of adding a “shuffle” button to rearrange the tiles if you get really stuck. It’s theoretically possible to get in an unwinnable state where you can’t swap two tiles

Perhaps do what you showed at the link, but only activate it on long tap-and-hold?

That is, if you hover a piece over some spot for X seconds, then it will shuffle other pieces out of the way.
