Tricked myself up a couple of times because I was using colors and letters to track different constraints and neglected to acknowledge that the color and letter could be the same thing. It was a lot to keep in my mind at once, but that created a really pleasant challenge that, while tough, wasn't insurmountable! Thanks so much for setting!

Never used the top left arrow, otherwise excellent ruleset and puzzle

I found this break in quite challenging, and had to restart a couple of times, until I noticed I had overlooked a rule. Then it was challenging still, but at least doable ????
Lovely puzzle, thank you!

Wow, this was rather a 4 star for me. I had to start over twice ...
... but very nice!

Hard but fair. Took a while to break in and then flowed very quickly. A low 4* difficulty for me.

Brutal for me. 104 min. But very satisfying in the end. Thank you for sharing!
