Nibbler is an old arcade game classic that's a cross between Pac-Man and Snake

Nibbler Remake

The object is to navigate a snake through an enclosed maze, while consuming apples along the way. The length of the snake increases with each apple consumed, making the game more difficult. The player must avoid colliding with the snake's own body sections. When the snake hits a wall, it stalls and rapidly runs down the level timer. After all the apples on the screen have been eaten, the player progresses to the next maze.

Snake grow big very quickly, making completing a maze a matter of mastering every maze, it is possible to eat all apples without colliding with the snake's own body sections as long you make the correct directions.

As the maze is panned you will have to rely on your memory were your tail and the rest of your snake body is as it is hidden from view, failing to remember were the rest of you could result in colliding with the snake's own body sections.

Capsules will fall down the screen as you navigate threw the maze, if eaten will give you either:-

... Quick Exit Point "located at the bottom of the maze"
... Slow down the snake
... Extra Time
... Crash Diet "shortens your length back down"

On every 7 mazes completed your speed increases, faster and faster were it becomes a matter of memory and quick reflexes to navigate the maze.
