The thread title really does need to be updated to reflect it's current release.
The latest 1.1 experimental update has broken one major option - invert mouse has completely disappeared from the options menu! Total game breaker as my brain can't cope with it not inverted

. The consensus is that they broke it when adding controller support.
Thankfully there's a fix:
Go to %LocalAppData%\FactoryGame\Saved\Config\Windows and open Input.ini
Paste in the following:
[/Script/Engine.InputSettings]
AxisConfig=(AxisKeyName="MouseX",AxisProperties=(DeadZone=0.000000,Sensitivity=0.034167,Exponent=1.000000,bInvert=False))
AxisConfig=(AxisKeyName="MouseY",AxisProperties=(DeadZone=0.000000,Sensitivity=0.034167,Exponent=1.000000,bInvert=True))
Thankfully it fixes it for me, otherwise I would have had to revert to 1.0 and do without all the great added features of 1.1. The updated blueprint mechanics (linking conveyors, train lines, pipes) and vertical nudge all make building things so much easier.
Great game all-in-all, I've got over 450 hours awesomely "sinked" and on Phase 5 now. Taking my time with it lol.
