Uwu ABCs Game
Match the pictograms with their corresponding letters!
When you open the HTML file in a web browser, you'll see a grid of cards with pictograms on them. Clicking on a card will reveal the pictogram, and you can try to match each pictogram with its corresponding letter by clicking on another card. If you find a matching pair, they will remain flipped, otherwise, they will flip back after a second. The game ends when you match all the pairs, and you'll see a congratulatory message.
Enjoy playing!
