Just solved all puzzles, really enjoyable game! The rule set is creative, and the puzzles are brilliant for showcasing the rules and how the rules can interact with each other.

I always find the concept of witness-like to be interesting, but I also find myself not enjoying some of the witness-like games. After reading your puzzle design thoughts post, it became clear that I like games that are more communicative when it comes to teaching rules, and more deductive when it comes to puzzles. That's why I like Taiji but can't get into Insight.

I think you did exactly what you set out to do as mentioned in your post. I can often deduce a lot about a puzzle, what you call "deductive anchors", and from there I can see the solution intuitively. I still don't feel like I have good intuition, but I did it in the end.

I liked most of the puzzles, and the bonus puzzles in section H and I are my favourites. They can be very hard and unintuitive, and some took me over an hour to solve, but I'm surprised by how much I can deduce without excessive trial-and-error. F9 is the puzzle that I struggled the most with, I relied mostly on trial-and-error on that one.
