BUILD NOTE
HTML5 games can fail in WordPress for reasons that are invisible in a normal page preview. A page may publish successfully while JavaScript modules, images, fonts, or runtime data fail after the browser tries to start the game. Knowing the common failure points makes play pages easier to diagnose.
Practical note
One common problem is asset paths. Games often expect files to live next to index.html, but WordPress pages do not behave like a normal static folder. If a game is loaded from a ZIP runtime or media upload, CSS URLs, background images, fetch calls, and module chunks may need to be mapped carefully.
Another problem is layout. WordPress themes can constrain content to a narrow column, add header spacing, or change the available viewport height on mobile. A game canvas may technically load while still feeling broken because the playable area is squeezed or partially hidden.
The third problem is silent failure. If a script stops before the game appears, visitors need something useful on the page: a title, a loading message, project notes, and a way to report what they saw. That is why Diligesker’s Lab keeps troubleshooting text on play routes instead of leaving blank launch pages.
Checklist
- Check the public route, not only the editor preview.
- Keep project notes aligned with visible game behavior.
- Record meaningful visible changes in the update log.
