The object of Nino is to get your man, the puffy white cloud, from one side to the other without being attacked by the dark clouds. Good & evil theme.
Your man can move 2 squares at a time, while the black clouds can only move 1 square at a time.
The first set of challenges - that's about it. Then there are a whole slew of elements. See the windmills? Land on one of them and you can move another square. See the drooping sunflower? You will need to land on the fish tank to pick up some water, then land on the sunflower. Other elements you will face: smoke stacks and electrical grids. There could be more that I haven't seen yet. There are 200 levels. I've solved only 37 - because they get hard!
