Just noticed it references a controller so i guess it does.

it's digital controls for joystick, for keyboard player 1 I use: 5 insert credit, 1 -start game; m -attack k -jump
directions for moving character -wasd, for some reason spacebar is used to pick menu options.

On Windows 11, spacebar also does weird lettering with white background if I set k for the attack key (may be an accessibility feature) Edit: I fixed the problem. Turned out to be Windows PowerToys. A thing called quick accent. I turned it off and it was fixed.

For controls it supports player 1 and player 2, keyboard and controller reassignment
