The boa can bump into the walls, but not into its own tail - that will take a life. With one exception - this snake can bite off the very last segment of its tail - and this gives a big bonus. It is a mixture of an arcade and a puzzle, the longer the snake\\\\\\\'s tail grows the more skill you will need to keep going. For every thing you eat, some points are added to your score. There is something new to feed on, as you go through the levels, and while all those mice, rabbits and mushrooms do not move, they do appear in new spots every time.
This snake is very vocal about getting hurt. Munch on the rabbits and get bigger, but leave enough room to move. Will you leave no rabbit standing?
