As an AI text-based model, I can provide you with an example of how you can build a simple Mitsubishi racing game using JavaScript and HTML. Please note that this code is just a basic example and can be expanded upon or customized further to suit your needs. Here's the code:
This code sets up a basic structure for a racing game featuring a Mitsubishi car. The player can control the car using the left (37) and right (39) arrow keys. The goal is to avoid colliding with the obstacle block. If a collision occurs, an alert will be shown, and the player's car will be reset.
You can further enhance the game by adding more obstacles, levels, scoring, and graphics as per your requirements.
