To play you will use the directional buttons to move you around. To attack you will press the space bar but keep in mind if you don't have a weapon you can't attack. If you see any blue lights that are surrounding a weapon quickly get to them to collect the weapon. From there you will be able to actually attack with that weapon whenever you press the space bar.
