Isn't there joystick options for controlling Blockland automatically?
Use software/etc which should come with the controller to set the stick on the controller to be the "joystick's" movements and the buttons you like to Fire and Jet.
You may have trouble mapping every movement and action to a key, though. If your program lets you, you could hold a button and press up/left on the controller to move the brick or something.
How would you type, by the way?
EDIT: Report the topic or something to get it moved.
