A few thoughts after playing:

• If this was your first game it's great! I will say, I wish it was more complex or had some sort of twist. This was literally just matching cards which has been done many times before.
• I did experience an odd bug where the rows of cards slowly sinks downwards as you click other cards. They seem to reset after I click on one of them in that row though. This got really frustrating on the later levels.
• I experienced a bug where I made a match of cards but they didn't disappear, this might actually be because some of the cards look very similar, but aren't actually the same card.
• I wish the text boxes were closer and easier to read
• I wish the font was easier to read
• The menu at the bottom left didn't seem to work. I'm assuming that was to allow you to exit back to the main menu?
