As far as tile-matching Mah Jong games go, this is pretty pleasant with the music and variety of board layouts, and it's nice to see the developer is keeping up with changes in the OS and platform. It makes for a somewhat competent alternative to the popular but aging Kyodai Mahjongg on Windows. However, in playing this on my Mac with a Cinema Display, I find myself constantly distracted by the low resolution of the game's graphics. The tiles are fuzzy, the graphical scoreboard/toolbar has pixellated graphics, and the included backgrounds (at 1024x746 pixels) are really pretty low in resolution, especially when you consider than an entry level 13" MacBook has a native resolution of 1280x800. Even the smallest iMac today does 1680x1050. Sure, it allows you to use your own backgrounds, but it appears to scale them down judging from the sample I tried. I'd also like to see the ability to allow custom tiles. Mahjongg games are very popular, judging from how many developers have their own versions. With a bit more effort, this one has the potential to stand out above the others.
