Hi DanielLC! You can read the right commands in the description above, thanks
Does that mean x button on a controller? It would be good to make a button on the left side of the keyboard work, since people usually use the arrow keys with their right hand.
And I see that it says to use space to jump, but I find it a lot easier just to use up and there's no reason not to make that work too. In general, pressing a certain direction should make you go in that direction.
