I discovered Jelly No Puzzle, an amazing game, here on HN. It might have been this comment: https://news.ycombinator.com/item?id=13022093

Unfortunately, it's windows-only, and the only mobile-friendly remake is an Android app. (There's a nice web version, but it requires a mouse right-click to move blocks right.)

Well, no more! You can now play it on your iPhone.
