I love the first Aqua Forest (iTunes link) "game", which wasn't so much a game as it was a physics simulator with different liquids and solids. But Aqua Forest 2? It's more like a fancy marble game with water droplets.
You get two game modes, but one is basically just an endless version of the other. Your task is to use the accelerometer to guide the water droplet from a leaf into a container around obstacles. That's it. Just like the marble games.
The water effect actually looks pretty realistic, don't get me wrong, but it's disappointing to see that they didn't come up with a better physics simulator game, and instead just made another move-the-marble-into-the-hole game. It's $US5 in the App Store, but we prefer the original Aqua Forest for $US8. [iTunes]
