Sure! Here's an example of a simple Kirby game with a new power-up, implemented as a single HTML file using JavaScript and enclosed within `` tags:
<br><br>
<br>
<style>
#game-container {
width: 100vw;
height: 70vh;
justify-content: center;
align-items: center;
font-size: 64px;
}
</style>
<div id="game-container"></div>
In this game, Kirby (`⊂(◉‿◉)つ`) moves from left to right, and a power-up (`★`) appears at a random location. The objective is to collect the power-up by aligning Kirby with it. Each time a power-up is collected, the score increases, and an alert is shown with the updated score.
Please note that this is a basic implementation and can be expanded upon to add more gameplay elements, interactions, and graphical improvements.
