## Description
_Bombyx_ is a snake game where the player has to eat a certain amount of
fruit to advance to the next level. Eating fruit causes the snake to grow
longer and the player has to avoid crashing into the body or any of the walls
on the screen. There is a countdown that resets after a fruit has been eaten.
If the player doesn’t manage to eat another fruit before it runs out the
amount of fruit needed to complete the level increases. Once enough fruit has
been gobbled a hole opens up in the top wall that snake can escape through. In
addition to walls there are bouncing balls that have to avoided. The number of
these depends on the difficulty level chosen, from none on the easiest level
to twenty on the hardest. A life is lost when crashing into a wall, a bouncing
ball or the snake’s tail.
