Basic Snake HTML Game

Snake is a fun game to make as it doesn't require a lot of code (less than 100 lines with all comments removed). This is a basic implementation of the snake game, but it's missing a few things intentionally and they're left as further exploration for the reader.

Further Exploration

Score
- When the snake eats an apple, the score should increase by one. Use context.fillText() to display the score to the screen
Mobile and touchscreen support
Allow the game to be scalled down to a phone size. See https://codepen.io/straker/pen/VazMaL

	## Fix OneDrive for Mac CPU usage
	##
	## Seems this is still a problem 5 years later after I created this little gist.
	## I have long since stopped using OneDrive (luckily), but according to
	## comments below, I have added the new path for OfficeFileCache for macOS
	## Mojave (10.14) and Catalina (10.15).

	## Run this on macOS Mojave (10.14) and Catalina (10.15)
	find ~/Library/Containers/ -type d -name OfficeFileCache -exec rm -r {} +

	# Clean, simple, compatible and meaningful.
	# Tested on Linux, Unix and Windows under ANSI colors.
	# It is recommended to use with a dark background.
	# Colors: black, red, green, yellow, *blue, magenta, cyan, and white.
