Sure! Here's a basic implementation of a Tower Defense game with a soda theme, written in a single HTML file using JavaScript. Please note that this is a simplified version and may not include all the features you'd find in a complete Tower Defense game.
Tower Defense - Soda Version
In this game, the player's goal is to prevent the enemies (represented by red squares) from reaching the player base (represented by an orange square). The player can place towers (represented by green squares) on the grid to defeat the enemies. Enemies move towards the player base by 1 unit per second, and if an enemy reaches the player base, the player's base health decreases by 10. The player can place towers on empty cells by clicking on them.
Note: This is a basic implementation and can be expanded upon to add more features, levels, tower upgrades, and additional gameplay mechanics.
