Sex, Secrets & Used Tech: Possible Bug (Workarounds)
Short answer
No confirmed fix yet. Players suggest: unplug any controller and try the keyboard on its own, or check any 3rd party software isn't interfering.
The problem
I simply can't get past the second stage of phone repair because I can only navigate up and down; when I try to go sideways, nothing happens.
What players suggest
If you're on the keyboard it should just be W/S to go up and A/D to move left & right after you draw the first line, so I'd imaging a controller would follow the same idea on the left stick. If it's not working you should check to see if any other device is interfering i.e. unplug any controller and try the keyboard on its own, or check any 3rd party software isn't interfering.
Suggested fix (unconfirmed): Mark the game as private during the checkout process. Alternatively, go to your games list, select manage game, and mark it as private.
