Twister is the metaphor for me. I had to lock my orientation so that I could rotate the phone around to untie some of two and three finger ones.

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".

If only you didn't let your finger slip off the line

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.
