A youtube video I found a couple months ago says you have to "Add Star" at the top right with the 3 dots while logged into your Google account. Then you go to your google drive to favorites and then right-click the File and download it. Not sure if that still works tho. I use MegaUp instead with adblocker enabled.
It makes me think of a real-time Fallout game. (I mean, the first ones in 2D.)
