Publishing checklist: make the game page useful before it goes public.

1. Write a title and description that match the game

A game page should not only say "A fast browser game." That is too generic. The description should explain what the player does, what makes the game different and which controls matter.

<title>Flying Bird - Supagames</title>
<meta name="description"
      content="Tap or press Space to keep the bird in the air, dodge pipe gaps and chase your best score in this quick browser arcade game.">
<link rel="canonical" href="https://supagamesai.com/games/lvl01/07-flying-bird.html">

Canonical URLs are especially important for index pages. If `/learn/index.html` says the canonical URL is `/learn/`, the sitemap should list `/learn/`. Otherwise tools can report alternate pages that are technically correct but noisy.

2. Put controls and goals near the game

Players should not need to guess whether Space jumps, attacks, opens a journal or scrolls the page. Every game page should answer three questions: What is the goal? How do I control it? How do I restart or continue?

<section class="game-help" aria-label="How to play">
  <h2>How to play</h2>
  <p><strong>Goal:</strong> Dodge the pipes and survive as long as possible.</p>
  <p><strong>Controls:</strong> Click, tap or press Space to flap.</p>
  <p><strong>Tip:</strong> Small taps are safer than holding a rhythm too high.</p>
</section>

This kind of text helps players and also gives the page real explanatory value. It is better than publishing a silent canvas with no context.

3. Test the console before publishing

A game can look fine for two seconds and still spam the console every frame. Repeated errors hurt gameplay, slow the browser and make maintenance miserable. At minimum, test load, first input, win state, lose state and restart.

window.addEventListener("error", function(event) {
    console.error("Game error:", event.message, event.filename, event.lineno);
});

window.addEventListener("unhandledrejection", function(event) {
    console.error("Unhandled promise rejection:", event.reason);
});

This snippet is not a replacement for proper testing, but during development it makes silent failures visible. In Supagames fixes, console traces often pointed directly to missing variables, broken event objects or UI elements that were renamed.

4. Add the page to discovery only when it is playable

Public discovery should include games that load, explain themselves and respond to input. Empty drafts should stay out of navigation and sitemaps until they are useful. This protects visitors and helps the site avoid low-value signals.

$trackedLearnFiles = Get-TrackedPaths -RepoRoot $repoRoot -Pattern 'learn/*.html'

foreach ($learnPath in ($trackedLearnFiles | Sort-Object)) {
    $learnLoc = '/' + $learnPath.Replace('\', '/')
    if ($learnLoc -eq '/learn/index.html') {
        $learnLoc = '/learn/'
    }

    $sitemapEntries.Add([pscustomobject]@{
        loc = $learnLoc
        priority = '0.7'
        changefreq = 'monthly'
    }) | Out-Null
}

Source pattern: Supagames sitemap generator.

The same idea applies to game levels. If a level index links to games that do not work, visitors bounce and crawlers see thin pages. Better to publish fewer working pages than many unfinished ones.

5. Accessibility and mobile checks

• Every canvas game should have nearby text explaining the goal and controls.
• Keyboard controls should not break text inputs, comment forms or search fields.
• Touch controls should be large enough and should not cover critical action.
• Buttons should be real `button` elements when they perform actions.
• Color alone should not be the only clue for puzzle solutions when text labels are possible.
• The game should remain understandable if ads are blocked or delayed.

6. Final publish checklist

1. Open the page locally and play at least one full loop: start, fail, restart, win if possible.
2. Check the browser console after interacting with the game.
3. Verify mobile controls or touch input in a narrow viewport.
4. Confirm title, meta description and canonical URL.
5. Make sure the game appears in the right index and the sitemap only after it is playable.
6. Run any available scripts such as catalog generation or page quality tests.

Publishing is not only deployment. It is the moment where game design, user experience, technical QA and site quality meet. A game page that explains itself is easier to play, easier to maintain and more valuable than a bare canvas.

7. Minimum content for a serious game page

A strong game page does not need a long essay, but it should contain enough original information to help the player. At minimum, add a short intro, controls, objective, tips, and what makes the game different from nearby games. If the game is part of a level theme, explain that connection.

<section class="game-notes">
  <h2>Design notes</h2>
  <p>This level focuses on timing and small recovery windows. The first wave is slow so new players can learn the controls before hazards combine.</p>
  <p>The best strategy is to stay low, flap early and avoid over-correcting near pipe gaps.</p>
</section>

That kind of text is useful to a human and it is honest about the game. It also gives maintainers a place to document intended behavior, which makes future bug reports easier to evaluate.

8. What to check after deployment

Local testing is necessary, but deployment can still reveal cache, path and canonical issues. After pushing, open the live URL with a cache-busting query, check that CSS and scripts load, then inspect the canonical tag. If a page is meant to be indexed, make sure it is reachable from navigation or a sitemap.

const canonical = document.querySelector('link[rel="canonical"]')?.href;
const h1 = document.querySelector("h1")?.textContent.trim();
console.log({ canonical, h1, title: document.title });

If live content differs from local content, suspect caching or deployment delay before rewriting code. This happened often enough in Supagames work that cache-busting query strings became part of the verification habit.
