I'd like to raise this issue again. Most games don't have a rating button on mobile, even though they can be rated otherwise. It's hidden by the Comments button as shown in the above post (and the other buttons - it might be visible if the author has only one game and so the button to go to their profile doesn't show up, for example). I circumvent it by using the PC site on mobile, but it's inconvenient and seems like a relatively easy GUI fix.

As far as I know the site changes by size with css. You can simulate this by shrinking your browser window on pc so it is higher than wide and smallish of resolution by zooming in.

In other words: your mobile screens ain't wide enough ;-b
