I remember seeing tis style of card game first in super Mario 2(though don't know where or if this style of card game came from that) but I was never really a big fan of it of course it has it purpose for a memory game. very helpful for the kiddies or for adults with memory problems. But you did a good job it runs well. I didn't notice a lag in points gained or lost, or the timer skipping at all. so as far as I noticed the game runs well and the art on the card isn't too simple they do pop out a bit. good job. keep up the good work :D
