AT THE MOMENT, NOT COLOR BLIND FRIENDLY
THIS GAME RELIES ON COLOR IDENTIFICATION!.
...

Original Description..
Brain Effort - Using the Stroop Test.
A word flashes on the screen, you then select the color matching the question to the word.
What happens, your brain comes in conflict between the part that reads and the part that
recognizes colors, this forces your pre-frontal cortex to resolve the issue, which means that it
takes an Effort and you are forcing your brain to use the prefrontal cortex.
