It needs sound
This is a fairly basic card game. Though it does look nice, and plays well enough.
There are no sound effects at all. No high score screen. The help text is not complete, and cuts off mid sentence.
Get rid of the "free advertisement" text displayed on the game screen. ( "GoDB Tech", "Powered by GoDB" ) Users do not want to be constantly distracted by text like that on the playing interface. Put that sort of information in the Help. The average user could care less what a game is Powered By. And the ones that do care, should be able to find that sort of information in the Help. Or on the developers web site.
