@mathgrant @edderiofer I never knew you had a blog! The concept is pretty cool but after I've completed it in 3 minutes, it's very limited.

This tweet refers to the previous puzzle, which I did say was trivial. So have a harder Akari, if you think Akari in general is boring and useful only for eye-candy.

Meanwhile, here's what my father said about it:

Congratulations for your new puzzle! I looked at it, and to be honest, I have no idea how to start. I just wonder how many people in this planet could solve this puzzle? How long will they take?

Answer: Many people, and 3 minutes.
