For the controls, here are the options:
I'd assume that's what they meant.Up,Down,Left,Right+Spacebar. That's how it looks on the Header Image.
It seems there's a confusion because of the way it's written.
In English it reads
"Controls are optional" which can be understood as you can pick and mix.
However in Spanish it says "
You have three options for control" understood as you can pick one and only one.
I hope they clarify soon.
