There are 26 default levels, custom levels and level editor options that allow you to create your very own level. Even the achievements available in the game make the game more appealing. The blocks seen on the platforms, change shapes on being clicked and your challenge is to make use of their shape changing abilities to get them to platforms matching their own colors. The setups of newer levels keep getting more and more complex, which means the difficulties keep increasing. I am sure you will not complain because that is the trend followed by most quality games as this one. Complete each level in least amount of time for maximum scores.
