Certainly! Here's a simplified version of Bloons Tower Defense 6 implemented as a single HTML file using JavaScript:
In this simplified version, balloons are represented as red squares, player's score and lives are initialized, and the game continuously updates the balloon positions. You can modify and expand the code to add more game mechanics, towers, and interactions.
Please note that this is a basic starting point and doesn't include all the features of the actual Bloons Tower Defense 6 game.
