actually you can solve it without developers, just use the information given in the console tab to find the cause of the problem
Alright. Downloading from front page gives the game as an application that crashes with white screen before ever loading. Downloading from the official site gives an HTML file that does give access to the main menu, but trying to play the game just goes to a black screen. Opening the console provides:
"
Access to script at '[-my computer files-]/torture-chamber-master/game/system/scripts/Util.js' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, isolated-app, chrome-extension, chrome, https, chrome-untrusted.
Failed to load resource: net::ERR_FAILED
"
Is that what you had before fixing your problem?
