Thanks for playing! that's really good! my lowest is 24 moves, you should share your score with reddit!

That should not be possible. I wrote a program that looked for the minimal solution brute force. 22 is the minimum.
This solution
a2, b4, c3, c2, d3, d2, d1, c2, c3, d3, d2, c2, d4, d3, c3, d4, c2, b2, c3, a2, a1, b2
would look like your solution but has 22 moves. There is a second way to get 22 moves but not less.
Have you found a bug or edited the Image?
You got me! It's a bug. My solution is 22 moves, but I did it the other way, where instead of d4, I did c3, moving the rooks in a circle. This solution is much faster and more consistent to perform, and I was trying to get the lowest time.
The bug is that if you go fast enough (possible to do with a mouse but much easier with a touchscreen device), the game doesn't count your moves correctly and misses a move somewhere. I am not sure where exactly the move gets skipped, but my best guess is the first queen move was not counted, because I moved the piece before the queen object was visible.
Thanks for verifying the quickest solution is 22 moves! Very cool.
Also just realizing that the image I sent was of the solution you said. I did it both ways in 4 seconds and I can't get lower.
Thanks for finding the bug! I'll push a fix soon!
