Moving the colourful worm you need to eat coloured fruits and beware of obstacles.
You should eat three similar fruits several times to complete a level. Game control is provided by mouse cursor appearing as a carrot. The hungry worm is always trying to bite off a piece of a lush carrot. Direct the cursor so the worm could eat fruits but you should not allow the worm to bite a cursor itself because it causes the reduce of health level. Some levels may be passed only by means of smart worm controlling but during most levels you will additionally have to logically think over the passing process.
You have got a lot of bonuses in the game which make gameplay more interesting.
The game is not that easy but it draws in, so be ready not to have passed some levels at first try.
