Use the arrow keys to move away from the giant block. If you get touched by that giant block you will lose health. If you're heath =0 than you die. There are two levels one level the block is smaller the second level the block is bigger. Also, to undo the shield you press the 1 key.
HUGE shout out to AsiaLaRana who has been a huge help by staring and hearting all of my games.
