Fun game, full of ads... It's a puzzle solving game, like cut the rope. This time you create walls and try to make the water get to glass and fill it. The puzzles themselves are fun and creative, but sometimes they easier ones came after some that were really hard, they have balls, falling cups, hot walls that vaporize water, etc. In later levels they start to mis everything up, which is cool. The ads are a problem, to get hints you need coins, and you don't get any from actually playing the game, but from watching ads. Sometimes, the ads come after every level you beat, they really start to get annoying, especially when you get 3 easy stages.
