could use some tweaking
its well designed graphically and its interesting, it just has the problem that its too short.. if there were more tests and they could be grouped randomly or by choice it may make it better.

Challenging!
I have to say that this collection of games is fairly entertaining. It really makes you get concentrated in order to succeed. I specially liked the color challenge. It's a great way of coordinating both your visual perception and your cognitive skills.
Great work!
