Took me a few minutes to understand what exactly I was supposed to do but once I figured it out I reset and did it in 13:15. Pretty neat game. I'm not sure I could do it faster a second time, just because my approach is a bit trial-and-error. Some patterns were surprisingly elusive this way.

I actually think I would enjoy it more if the UI helped a bit more, like by marking the squares that were forbidden because of the queen.

Thanks. Regarding marking forbidden squares, apparently the whole point of the game is to develop visualization skills for chess (under Help, it references a grandmaster who recommends this exercise), so if it marked forbidden squares it would defeat the purpose a bit, I think!
