Poop ABCs Game
This game presents a series of questions where the user needs to guess the word that starts with a given letter represented by a pictogram. The user enters their answer in the text field and clicks the "Check" button to see if it's correct. They can then proceed to the next question using the "Next" button.
Note: This is a basic implementation. You can add more questions and customize the game further based on your requirements.
