Episode 3 boss strategy

You need to evade the boss' attacks first before you get a chance to damage him. When he jumps, it creates a shock wave. If he does a pirouette it will create 3 shock waves so use a double jump. When he slides just run to the edge of the area. When he rapidly jumps 3 times in a row, 3 icicles will drop from the ceiling. When the boss causes a stone circle to fall from the ceiling, hit all the ice cubes 3-4 times to launch them to the boss. There are 3 cubes in the first stage, 8 in the second and 12 in the third stage. When the boss has been hit by all the cubes, there will be 3 sequences where you have to memorize 3 buttons and press them at the right moment. After that pound away. Do this 3 times and the boss will be defeated. The game also auto-saves after each stage.
