Oh huh, from looking that up...
Does this link work: https://v6p9d9t4.ssl.hwcdn.net/html/1894526/index.html ? That's the direct link to the game file on the itch.io hosting servers, rather than the embedded-in-page one you get from the game page. It kinda sounds like Chrome doesn't like the part where they're on different servers, which I guess makes sense because that would technically make it a third-party cookie/site data thing.
