#Memory Flash Game by bjh-developer, built in Visual Studio Code, with Python 3

### Optimised for all IDE except for Jupyter Notebook! ###

#Let's make a game!
#The game plays like this: Each level, a series of numbers (0 to 9) will be flashed, and each number is flashed 
#at a regular interval (like blinking - show 1 number, clear it, show 2nd number, etc). 
#So level 1 has 1 number, level 2 has 2 and so on. When the entire series is shown
#we ask the player to answer, what were the numbers he/she saw. E.g. if he saw 1, 2, 3, his answer should be '123'.
#If he answers correctly, he goes on to the next level. If not, it's game over!
#To start the game, we can print 'Ready?' and wait for 1 second, and start flashing.

#We shall learn to organise our game and divide it up into specific tasks. And what is a block of code that does a
#specific task?
#Tasks:
#1. Start/Manage the game - start the game, and generally run the game
#2. Generate the series of numbers
#3. Flash the numbers
#4. Get the answer from the player
#5. Check the answer against the series (optional, we can put this in 1.)
