29//
30// Camera Display Games: Snake
31//
32// Start the game by:
33// MagicSnake snake;
34//
35// Controll the worm using right/left. Make sure, that the mouse pointer
36// is inside the canvas.
37//
38// Move the mouse pointer outside the canvas to pause the game.
39//
40// The pixel colors have the following meaning:
41// --------------------------------------------
42// Green: Food, collect all packages.
43// Red: Bombs, don't touch it!
44// Yellow: Transport, try it.
45// Magenta: Home, touch it to win the game.
46//
47// To restart the game use the context menu. It can only be accessed if
48// the game has been stopped (either because you win the game or because
49// you hit a bomb) With the context menu you can also toggle between
50// different camera layouts.
