lovely!
I didn't come to like Mahjong until recently but this peculiar version of it is awesome, really. A lot of variating layouts to choose from and with clear bricks.
In some other Mahjongs you can barely differ the different kinds -.-
The only thing I find missing is the lack of music. It doesn't have to be anything big or flashy but maybe some nice ambient asian styled loops would add a nice touch.
Also the online editor is on japaneese or chineese or something =P
