I have three issues with this game, otherwise it's easily the best mahjongg I've found on kongregate: the tests are a little faded and therefore difficult for me to see on a white background, I can't toggle the music and sound options, and the fact that there's only one layout is disappointing.
I don't like that you have to complete a layout to get to play another one, especially when they aren't necessarily winnable. I also highly dislike that when you lise, you return to the beginning, rather than the layout you lost on.
