A classic but...
It's the classical shangai and so nothing of new, but you added some nice features, like combo or the two way of play. You added a a storyline also. The graphic and sound are good too. Why don't you add a countdown to finish the level, and time bonus when someone finds couple or makes combo?
The game is really yours? I ask only because in the presentation of the game I can see that's presented by devilishfree site.
