Thanks for the feedback.
But I will keep it this way for all my games. Like the original Nintendo controller setup have always been left button = run, right button = jump.
I see. Well, it makes sense on a game controller, but on a keyboard, I jump with Z and run/shoot with X.
Maybe you can give an option for different/edit control schemes.
I struggle with the game a lot due to my muscle memory.
You can use a controller when playing it right here on itch or any emulator.
