See sushi sad, build sushi blockade, see sushi survive, and see sushi happy. In this game you must protect the lone little sushi by surrounding it in blocks. The fort will then undergo an attack and if your sushi is protected then you clear the level. If you fail to protect your sushi, it will die and you will fail the level. Keep trying. Sometimes there will be more than one sushi to protect and other times you may have more than one goal. For example, in one level you not only have to protect your sushi but you cannot let any of the blocks leave the scene.
