I've got a bad back. Being able to use the Mansions of Madness app via my Steam Machine on my TV would be a lot more convenient than hauling my laptop back and forth. It's not Steam OS supported as far as I know, so doesn't actually PLAY on the Steam Machine, it streams from the laptop. But if I can use the Steam controller to run the game on the laptop in the other room, that would be a serious bonus for me.
On the Steam Machine library page for the app, it says "Controller Configuration Required." But I get no information on "configured to what configuration." I get no cursor on the screen, and it doesn't respond to any controls I've been able to find.
Pretend I bought my Steam Machine used, so it came with no M for me to RTF. How do I make the app work, please? I'm sitting here with my newly-purchased Streets of Arkham set and want to get in a game within the next hour or so if possible.
