I second this. I assume there won't be updates for this game, but it's something to remember for future games. It's a simple accessibility feature. There should be an option in the menu for it, and/or auto-detect keyboard vs. controller based on buttons pressed. There should be 3 possible settings actually: Keyboard, Xbox, or Playstation.
Not everyone grew up with consoles. Plenty of people don't own a controller! Plenty more people choose to use the keyboard instead of a controller because they're more comfortable with it. For you a controller may be more enjoyable. For me it's the exact opposite. It's unwieldy and frustrating.
