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.
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)
