Sure! I can create a simple game for you where you can jump over spikes and even create your own levels. Here's the code for the HTML file that you can run on your smartphone:
This HTML code defines a canvas element where the game will be displayed. The script starting from the `
` tag contains the JavaScript code for the game logic.
The game allows you (the player) to jump over spikes using either mouse clicks or the spacebar key. The player character is represented by a blue rectangle, and the spikes are represented by red rectangles. The game updates the positions of the player and spikes in the `update()` function, and then redraws them on the canvas.
To create your own levels, you can modify the `spikes` array in the `init()` function to add or remove spikes at different positions on the canvas.
Please note that this is a basic example, and you can enhance it further with additional features and graphical elements based on your requirements.
