Definitely a fun game! My friends are a addicted to it! It challenges the player's mind, educating them on critical thinking, logic and most of all, creativity! With many mind bending puzzles and hundreds of options to complete each level, it's so much fun and enticing! From the first moment I've played it, I couldn't stop. It gets more interesting and interesting the more you play. The first world is easy, but somewhat during the second world, it gets harder, and by the time you're on the fourth world, it's challenging! I would recommend it for kids ten and up, unless their is a super-genius four year old in your house. No doubt about it, the game is INCREDIBLE!
