Too easy.

First off, this type of game has been done many times before. Also, your colour scheme made it very easy to just look at the center of the screen when the green dots are present for a few moments while the timer is ticking down to see the same dots presented in magenta afterwards. Of course, if one moves his eyes, the effect fails, but my point remains.

Meh

Kinda boring, but well assembled.

been done

this has been done alot.
It annoys me that theres a game down my local pub like this, but if you win you get money, i did your game straight off, and im still skint :(

addictive though
(as long as you dont move your eyes, then they change colour you can still see where they were, its like an optical illusion! if that was deliberate then well done)
