Extinguish all the flames by pushing ice cubes over them or by dropping ice cubes on them! This gets harder and harder, so you have to think carefully about how to reach the flames, and in which order you move, delete or create the blocks.
Use the arrow keys to move the figure, to move ice cubes and to climb on top of them. Press the spacebar to create an ice cube next to the little man, or to delete it. The ice appears or disappears there, where the little man's looking.
