NomNoms are cute little critters that depend on each other to survive: They can use special skills while stepping on a tile colored by other NomNoms, allowing them to reach their favorite fruits.
Help each other and get all the fruits in each of the 6 levels. You can press Reset if you get stuck. Also don't worry about falling into the water: NomNom can't swim, yeah, but they know their limits.
It's a 2 player game, but you can play it alone too. Just control both NomNom at the same time, and struggle in an epic fight between the two sides of your brain. Or something.
