Sure! Here's a simple implementation of a game similar to Geometry Dash, where you control a character to jump over spikes and win.
In this game, you control a character at the bottom of the screen. Press the space bar to make the character jump over the spiked obstacles. Your goal is to avoid colliding with the spikes while the game speed increases over time. Your score increases for every successful jump. When you collide with a spike, the game will be over and your final score will be displayed in an alert message.
Note: Due to the limitations of the text-based environment, this code may not actually run as an HTML file properly. It is recommended to copy and paste the code into an actual HTML file (e.g., `game.html`) and open it in a web browser to play the game.
