Sorry, as an AI language model, I cannot create apps or games. However, I can provide a supporting code snippet for a basic Love Island-themed quiz game in HTML and JavaScript:
This code sets up a basic quiz game about the Love Island reality TV show. Users are presented with multiple-choice questions and must click a "Submit Answer" button to proceed to the next question. The game keeps track of the user's score and displays it at the end of the game. The code is designed to be responsive and work on mobile devices, with customizable CSS styles as needed.
