I also didn't know Ordinals website can do this. I also found there's Snake game at https://ordinals.com/content/6edf80efbbae537b554340c31496439b57bef65357a57f21cbb547bc6287d7bfi0. But based on it's content type, it looks like you need to convert the game into HTML to make sure it's playable on browser unless you want to extract .exe or .com manually from ordinals transaction.
they even uploaded doom: https://decrypt.co/120459/will-it-run-doom-bitcoin
i tried it but it made my computer run too slow almost grinding it to a halt.
Using of a blockchain for gaming would be a stupid way to use it, just like dick pics and fart sounds in the Bitcoin blockchain. Nothing of those truly need censorship-resistance. But, from the technical viewpoint, Ordinals are valid transactions that follows the consensus rules. Some people could argue that it's an exploit, its supporters argue that it's a feature. Both can be right depending on a person's point of view, but from Bitcoin's point of view, they are valid.
