Great puzzle concept! I got stuck at the end of level 7 after finishing the puzzle. I'm not sure if this is the end of just the game didn't realize that I was finished.
yes. I also noticed that bug. I have just uploaded a new version. I checked that level and seems to be working now. No, that is not end of game. There are 14 levels, ending with 9x9 boards. So if you are not yet bored with them, could you try to pass that level again? thanks in advance.
I also encourage to tick challenge mode, to get swaps and moves count:) no highscores there but a self challenge could be:)
