Using Firefox 128.0.3 on Ubuntu 22.04 LTS, this freezes the browser hard, right after I click the door and get the “don’t know if it’s even coherent” text. At that point, Firefox is using over 100% of CPU, according to top. Using Chromium 127.0.6533.88 on the same OS, the browser doesn’t freeze quite as hard, but the game stops at the same point and Chromium also uses ridiculous amounts of CPU.
I’m assuming this isn’t the intended behavior, and it’s not something I’ve seen with other web-playable games on these browsers.
