You can press: left arrow, right arrow, down arrow, up arrow, space, a,r,m,and f! (If you press a certain key you can unlock a bonus scene!) Press F last because if you don't it makes no sense.
The key to the bonus scene is not a number. That is my only hint. And when I say "You thought I would say fortnite XD No way" I don't mean any hard feelings. I just don't have that game. The key you have to press is the number 9 ;) I said not a number to trick you.
