Game not working past title screen.
After "start" pressed buttons "options" and "credits" do not work.
Clicking "remove building" or "dig" creates error in console "curv is undefined".
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.
