great
I like the way there is a time limit. The levels are good and its great the way each one has more pairs to find than the one before. good sound effect when you get a pair but after you get a pair, if your trying to move quickly because you are running out of time, it wont let you click the next pair straight away, you have to pause for a second first. Some background music is the only other thing i can think of to make it any better.
