If you own a controller or maybe it works even without? , then steam itself has a feature by which you can change input layouts. I have created one such layout and shared it with the Community. It adapts an XBOX Controller to the Control Scheme of the Game.

To use it, or make your own , right click on the game on steam and go to properties .

A New window will pop up.

On the Left side, there will be the sub-Point "Controllers"

In that Sub-Menu, on the right side, will be a drop down menu - choose steam overwrite.

In the text above the Controller list and the afore mentioned button, is a hyper link named "Controllerkonfigurator" click that

Click on your current Layout, and multiple options should appear. At the very top is the Community Option, Choose that and select my Layout.

Done!

Hope this helped!
