LOL, I think I physical feel the conflict between the left and right in my head now. The instant the word popped onto the screen, my hand would jerk to whatever color it said until my brain overrode my hand. A few times, my hand seemed to rebel against my brain and would move the mouse over to the wrong word, but my finger wouldn't click.
Took me two tries because, like usual with these flash games, I didn't read the instructions the first time.
The cake is a lie.
