Wondering how is this game?

In this game, the two characters , Fire boy and Water girl , have a mission to collect all the diamonds and reach the level usitele to move to the next episode using certain processes and activating certain mechanisms. There are also several kinds of levels. In levels marked with a hexagon on large map , your mission is to direct as soon as possible to the two portals , collecting all the diamonds . Levels marked with a small triangle may seem very similar , but what makes them difficult is that Fire boy and Water girl suddenly moves so that the risks of error are large . In levelurile marked with a diamond , the mission is to collect two green diamond , and then to move to the doors of " output " . And , lastly , the levels marked with a diamond there is no light! The road will be shown by some bright platforms . In large part, the same principle exists in all levels : play in two or only one player , activate all the mechanisms , valves , move all laditele to be able to collect all the diamonds and reach the door .
