The levels where intentionally nerfed to the ground to ensure the player would be able to reach the final fight seems that might have gone a little overboard. (But some people seem to have enjoyed that aspect?) As for the pickaxe the goal was to jump and attack her while mid air as its hitbox is actually rather large (abit larger than the blue slash in front of her) but yes the osu weapon and the microphone where poorly balanced and felt too challenging to use.
