This would be a fun game with some UX improvements. It's extremely frustrating when the reason I can't finish a puzzle is because my finger slipped off the line and not because I just don't know the solution. I stopped playing because of how frustrating that was.
Totally agree, the dexterity is what makes it fun. I was thinking about how a larger screen would help, or if I had longer fingers, or if I cut my nails it'd be better. The annoying fails build me toward a sweet victory. good rush.
Also, the cost of failing is not much, quick iterations. You just have to remember what you did.
No, they're not the same. In Jenga you usually lose in a way that you know could have been avoided. "If I had just held my hand still" or whatever. That is not what this is. This game is frustrating because it was poorly designed not because it is "hard".
