Attention Span

This game is a great tool to improve your memory and attention span.
Once you click to start, the prompt will indicate that 
it is my turn. 

You will see a sequence of flashes. Once I am done, 
the prompt will indicate that it is your turn. 

You have to repeat the sequence in the same order shown 
to you. 


Once you repeat the sequence correctly, you will level up to a longer sequence.
Test your memory and find out how long of a sequence can you repeat exactly.
