What's annoying and counter to popular convention / user expectations is that you have to keep your finger in the established path to keep grip of the "ball". (S'pecially given your finger often blocks the view of it).
I'm not sure that the game would work without this restriction. If you kept grip of the ball regardless of if your finger was on the path none of the game's puzzles would work since you could just move your fingers wherever you wanted without losing the ball.
For me it wasn't that the slide doesn't stay in place (that much is expected), but that if you deviate from the path it immediately slips back to the beginning. That's a bit anti-pattern w.r.t. typical slides that either have a forgiveness zone around the element or update to the point on the slide nearest to the gesture point.
Uhm haha. On behalf of our community I would like to say that I was perfectly capable of understanding this mechanism thank you. Pretty sure the reason for the unintuitiveness for some people must rely on something else entirely.
Android stock maybe. Android as delivered by various vendors? It depends. I've seen variations of this mechanism pop up - including ones requiring to keep the finger on the path or else you "lose the ball", and that one was in the phone UI, where you needed to swipe to accept or reject a call!
Definitely one of the core challenges of the game, and understandably not to everyone’s taste. I learned that I inadvertently swipe in a slight arc on the first puzzle and enjoyed learning to move precisely.
