Where's My Water 2 looks and plays great (pictures)

Just like the original game, you'll need to carve a path to let the liquid flow to the goal. But new challenges have you avoid the ducks entirely once you've completed the level the usual way.

After your first play of a level, new challenges are unlocked to add to the gameplay.

Duck Rush levels have you carving through the dirt as the window scrolls downward so you have to make decisions on where to direct the flow quickly.

Earn achievements to get themed duckies. They have no other use besides marking where you are on the map, but I think it's a fun system for achievements.

I saw much longer wait times than this, but your options here are to buy an energy refill for 99 cents, connect to Facebook for one free refill (not available in this demo), or ask your Facebook friends for more energy. It is unclear what the cost is for your friends to give you more energy.
