Your fundamental game mechanic seems fine (though maybe a little derivative, as I'm sure you're aware). I think the major problem is that the app doesn't feel as smooth as drop7, etc. The winning games have a tremendous sense of style. With a few relatively minor changes, I think the game would be a lot more attractive. 1) Get a more pleasing set of sounds. The high-pitched screeching you are going with currently when blocks blow up is torture for me. I like the sound when you die, however. 2) Make a game-mode for the beginner where it is easy to figure out the game mechanic. I died within a few rounds each time I tried. (Start with all little red block or whatever...) Make this auto-start the first time the game is opened. 3) Moves are too clunky. The blocks move to the side of the screen too slowly after the user presses a button. I would make this 3-4 times faster, or just eliminate it. Blocks also maybe fall a bit too slowly-- I would eliminate the pause before they fall. 4) There is too much visual clutter on the screen. Its nice of you to show the time and battery life on top, but this clashes with your application. Also, the colors of the score, and "Menu" "Help", etc. all clash a bit. Good luck-- I think you fundamentally have a good game, and with just a bit of a nicer interface, you could do very well.
