The name is OpenLara (https://github.com/XProger/OpenLara ) and you can try out the WebGL build directly on your web browser on: http://xproger.info/projects/OpenLara/ . The web version works amazingly well on my Pixel 7a with touch controls (you have to click on the “go fullscreen” button) using Firefox as a browser.
Yet, it is a very not-really-good idea to run stuff on a web browser. Web browsers are a notoriously insecure, slow platform with controls (“Back”, “Reload”, …) which are not optimized to run applications.
edit: I did not expect that the “modern web” crowd would now come here to berate (and downvote) me for the sacrilege of not unconditionally considering web browsers to be the very best piece of software for every purpose. My fault, sorry. I’m out of here, this is pointless.
Let me get this straight, you think running something in a browser with its sandboxed design, is somehow less secure than downloading executables off of GitHub?
Yes, because browser sandboxes will NEVER be as secure as kernel sandboxes.
(Run the browser in the kernel sandbox)
