I sometimes play Doors on a mobile, but usually on a computer. It's a lot easier (and faster!) to do it on a computer, but the thing is this computer is old and can't download newer versions of screen recorders which limits my options. There is a very nice screen recorder I have installed, but the thing is it only comes with video, it doesn't have any volume. I heard there's an extension for it that allows audio but I heard somewhere that's a virus. Are speedruns with the volume of the screen recording muted allowed, or would it be rejected?
