5x5 | 101 Moves | 2:05. The first time I played, I was arranging them in just so that they sequentially match, didn't realize they needed to be 1 in top left, then 2, etc. That change, and ability to copy final results, might be nice. I like this better than a sliding puzzle, less frustrating :)
My first game, I got to round two, but was figuring stuff out as I went along. My second game, I knew more what to do, was still learning, but managed to get all the way to the end and barely win the last match. Fun game, lots of stuff to figure out, good replay value. A YouTube video, showing at least a playthrough for the first two or three rounds, may be helpful to new players.
