Sure! Here's an example of a simple game that meets your requirements:

You can copy and paste the above code into a single HTML file and open it in a web browser to play the game. The game uses the canvas element to render the graphics. You can tap the spacebar to make the square jump over the obstacles. There are buttons to change the colors of the square, and when you collide with an obstacle, a restart button will appear to restart the game.
