Thanks for the kind words!
Its nice that you noticed the exception on the last line. Very much intended for risk. There was also a bit of fun factor, with dot moving around often by the time you are ready to close the loop, there's no "safe" line back to the first dot. needing such skill, while perhaps more skill based would less fun/too challenging (or so I felt).
Funny thing about the pause Idea is that's what I initially intended. (or at least transition between levels) but when I first made levels changes it wasn't that bad. With color transition & appearance animation, it felt fairly "separate" though I did wish fora bit more delay between levels, at that point it wasn't much of a priority.
Some stationary levels do comeback although pretty far in ~17-20(?) I'm not going to pretend it was my genius plan, at that point levels are random and static levels can and do happen. They are fun and do give some reprieve. Whats cool about those is there's no stress of dot crossing lines. but with so many dots, you can take an order that breaks (line or dot cross) or just get a fulfilling full combo!
