The objective of the game is to save as many people as possible from a sinking boat. You accomplish this by tilting the boat (your iPhone or iPod Touch) and sliding as many people as you can into the lifeboats. Of course, your precision can only be so good, and many of the people tend to fall right off the boat. To recover them, you simply tap on them to bring them back into the boat before they drown or the sharks get them.
As you earn money during career mode, you can buy upgrades to improve the ship's handling, time and ability of your passengers to swim. The game comes with both career and quickplay modes.
Early forum reactions are positive and are being collected in the discussion thread. The game is certainly very well produced, but the actual gameplay is very simple and may not appeal to everyone. The video above should give you a good idea of how the game plays.
