Each level requires you to help a Sunflower to find the way out of dead block condition.  Lead it through all 30 levels of the game and the Sunflower will shine of happiness. You have only one tool to use – a saw, which let you saw everything what is supposed to be sawed. But except of the saw you will need to apply your logic and sharpness to cope with the task. Be careful with the mushrooms! If the Sunflower eats them the laws of physics will be changed for it. Also stay away from the teleports – they can lead it to the most unexpected way.
