The game seems broken for keyboard.
So I launched the game for the first time, and started the quest. I got stuck on the first door where you need to select your "difficulty shield".
I couldn't enter the black portal because I didnt know how to jump to reach it, so I just manually closed the game. When I restarted it, I couldnt start the quest again because my keyboard buttons weren't working. I couldn't use the arrow keys to select the buttons on the menu, and pressing enter/spacebar/whatever key its supposed to be to confirm didn't work.
