This is a decent game and it runs smooth... but I am unable to figure out why it has a mature rating.

nice

I love the way you made it really nice!

Very good!

Hey! That was a really good memory game, I just LOVED the music, although it was only one tune, it totally matched with esence of the game. Please, don't get me wrong with this, but maybe more levels would make it even more great. I would love to see another memory game in this style. Honestly, great work! Keep it up!
