Looking at the code, I can see the updateHighScore function exists but it's only called in one specific game over scenario (bug collision). Let me fix this by ensuring high scores are updated in all game over cases and also during successful challenge completions.

Fixed the high score bug! 🎯

The issue was that updateHighScore was only called in one specific game over scenario. Now it will update the high score:

1. On all game over conditions (wall collision, self collision, bug corruption)
2. When completing challenges that result in a new high score
3. Only when the new score is actually higher than the current high score

The high score should now properly save to the database whenever you achieve a new personal best! 🏆

I'll help you remove any email exposure from public URLs and ensure emails are kept private. Let me check the current code and make the necessary changes.

Security improvements implemented! 🔒

Changes made to protect email privacy:

1. Leaderboard: Removed email from the database query - now only fetches id, username, high_score, challenges_completed, created_at
2. User Type: Made email optional in the public User type and added a separate PrivateUser type for when email is actually needed
3. Logging: Updated console logs to only show usernames instead of full user objects that might contain emails
4. Profile Fetching: Added safer logging that doesn't expose the full user object

For the Vercel URL:

The URL is automatically generated by Vercel based on your project name and deployment. To change it:

1. Go to your Vercel dashboard → Project Settings → Domains
2. Add a custom domain (like codecquest.yourdomain.com) or
3. Change the project name in Settings → General → Project Name to something like code-quest-game

The email in URLs typically comes from the project name or git repository name. You can rename the project in Vercel to get a cleaner URL like code-quest-game.vercel.app instead of one with your email.

All user emails are now kept private and won't appear in any public displays or logs! 🛡️
