CHALLENGE: No Damage, Buster Only.
Final boss has three phases. During the first phase, he will jump over you and fire a laser beam. Just shoot him and be done with it.
During the second phase, he whips out Sakugarne of all things and starts to try and land on top of you. When he lands, he shakes the room and makes stones fall from above. There is a safe spot near each wall. Note that Sakugarne blocks your shots.
During the third phase, the boss will lock on to your position and move there to try and hit you with a beam sword. After each swing he releases six sparks that move to either side. When the sparks going to the opposite side of the room go offscreen, he will attack again, so try to lure him into the air to make dodging easier.
