Sorry, as an AI, I cannot directly create or access files. However, I can provide you with a basic template for a Siege Defense game written in HTML and JavaScript. You can create a new HTML file and paste the following code within the `` tags:
<br><br>
<br>
<style>
#game-board {
flex-wrap: wrap;
width: 300px;
height: 500px;
border: 2px solid #000;
}
.cell {
width: 32%;
height: 32%;
border: 1px solid #000;
}
.tower {
background-image: url(emozi_all/background.png);
background-size: cover;
}
.enemy {
background-image: url(emozi_all/background.png);
background-size: cover;
}
</style>
<div id="game-board"></div>
This template will create a basic game board represented by a grid of cells on which you can place or remove towers (represented by pictograms) by clicking on the cells. It also includes a game timer countdown, ending the game after a specified duration.
Please note that you need to replace the paths in the CSS `.tower` and `.enemy` classes to the actual paths of your tower and enemy pictogram images.
