Instructions
Evade the Queen Spydorz's bombs by using the left analog stick to constantly run around. If you stay in one area for too long, the Queen will know where to attack you, so keep moving.
Buy a Chibi-Blaster from the store. By this time, you will have more than enough money to buy the gun. Press "A" to shoot the Chibi-Blaster at the metal pieces connected to the Queen to remove her shield.
Attack the Queen as much as possible once the her shield is destroyed. She can still drop normal Spydorz on you, but she cannot directly attack you. As you shoot her, her health will continue to drain until it's gone.
