Let's begin by reviewing our objective.

Commit all the newly generated web files (including index.html, JS, and WASM files) to your Git repository and push the changes to the main branch on GitHub to trigger the deployment.

Next, we'll perform initial verification steps to understand the current state.

Before proceeding, ensure the following:

1. You have successfully completed the previous step of exporting your Pygame project to web files (index.html, .js, .wasm, etc.).
2. These generated web files are located within your local Git repository directory.
3. Your local Git repository is correctly configured with a remote pointing to your GitHub repository.
4. GitHub Pages is enabled for your repository, configured to deploy from the main branch and the correct directory (usually / or /docs) where your web files are located.

Now, let's build the solution by following the instructions to commit and push your web files.

Step by step checklist:

1. Stage all the newly generated or modified web files in your local Git repository.
2. Create a new commit with a descriptive message summarizing the addition of web files for deployment.
3. Push your committed changes from your local repository to the main branch on your remote GitHub repository.

The following documentation sections are going to be helpful:

• GitHub Pages
• GitHub Pages Configuration
• Deployment via Git Push

With the changes in place, let's re-verify our work to ensure it meets the specification.

Since this task involves triggering a remote deployment, verification requires checking the status on GitHub and the live website.

1. Go to your GitHub repository's "Settings" -> "Pages" section. Check the deployment status. It should indicate that your site is being built or is live.
2. Once the deployment is complete (this may take a few minutes), visit the GitHub Pages URL provided in the settings.
3. Verify that your Pygame game loads and runs correctly in your web browser at the live URL.
