I understand you're not finished but I have to assess this as it is now, not as you want it to be. I can't critique it based on a finished product that doesn't exist.
The game part is interesting and I like it,
as a game. This feels like a PopCap game to me. That said, if it was a PopCap game, the visuals would be far more polished. As they are, they look half finished, like a lot of it is placeholder graphics. However, it's far too competitive and the visual payoff isn't strong enough to be anything but a game.
So in summary: if you want this to be all about the visuals, you should dump the game entirely. Though I rather like it as a game. I might buy this if it was in the App Store.
