 Please review my DropZap web demo.  It's written using GWT.
alex_c: I really think you might be on to something.  It's just as much fun to play as any of the big hits in this genre I can think of - really is in the same class as Tetris, Bejeweled, etc.Some random thoughts:- I started reading the instructions, failed to visualize any of it, and said "screw it, I'll just start playing and pick it up as I go".  The good news is the gameplay itself is very intuitive.- appearances are SO important in the iPhone world.  If it looks like it's starting to pick up momentum, absolutely get a good designer on board and give it an overhaul.  I can easily see someone else take your gameplay, give it a lot of polish, and release an app that will leave yours in the dust - that would really suck.edit: just bought the iPhone version.  Well worth the $0.99.
