HTML5 metadata not loading properly on any marketplace


I tried to upload a little HTML5 game as an NFT, in the preview it loads completely fine - but once I upload it on test net only the HTML header is visible.

Is this something you can help me with?

Here is the link to the test token:



The HTML page seems to be working fine on chain: Seize them

It’s likely something on OpenSea’s side so I would recommend reaching out to their support team!

yes I saw.

So it’s indeed something that depends on OS?

Will try, thank you very much!
