I suspect that the device your on, the browser, does not support web workers. The main loops use a Web Worker, and I've yet to fully implement backwards compatibility for it. I'll be working on that, and will update the game when it's finished. Thank you very much for this feedback!
IMHO, I doubt that's main issue here. FF supports web workers for a long time (my current version is 101). I do disable them using uBO but:
1) I don't get CSP error about worker-src rule in console (which appeares whenever site tries to start web worker);
2) I excluded v6p9d9t4.ssl.hwcdn.net domain from uBO rule and other games that was requiring workers were working fine.
Rule in question:
*$csp=worker-src 'none',domain=~aniqit.com|~html.itch.zone|~twitch.tv|~v6p9d9t4.ssl.hwcdn.net|~captcha.website
Interesting, I think you'd have to exclude the exact page that the game plays on, the worker itself is built into the code of the game. Nevertheless, the fix I have planned should work for you, it's something I should have already done some time ago. I hope to have this and other things ready by the end of next week, I'll post an update about it when it's complete.
