Not too shabby
I think this a great effort. Granted, it is a very common concept and so SOME PEOPLE (below, perhaps?) will react negatively or quickly forget about it.
However, the coding works very well. Really, no glitches found or anything, which is quite uncommon with new submissions. I also like artwork. Though simple, the colors are nice and everything is very neatly placed and organized.
All in all, I think you have promising skills, and would love to see what you can accomplish when they're paired with a really original concept. :)

After flipping 3 cards, every other card I flip almost instantly flips back, making it hard to match anything.
