It has dropped to 99 cents and so I bought it, but I have to say that so far I'm disappointed. It isn't really much like the web flash game. Every level is just a blank screen. The only "splumes" that end up on the screen are the ones you shoot. It's almost interesting. The only thing you are going for is to complete levels as fast as you can. In fact you could take your time and finish a level in 2 days if you wanted. Finishing a level is just popping a certain number of bubbles (by matching 3 or more, of course). If the bubbles end up below the bottom line you have a few seconds to clear them from it or you lose. In case you haven't played Splume, the difference in this game is the physics. The bubbles sway and move and they stick to each other when they come in contact. Also the bubbles are of varying sizes. On the iPhone you also can affect them via tilting. The physics of the game are cool, but I think they should have made the game more like the web version. I'm curious what others think about it. Maybe it will grow on me. Also there is no sound, and seeing how they've dropped the price to 99 cents, I have to wonder if we'll ever get sound. This should be free if they aren't going to complete it, and without sound, it isn't complete.
