Other than already said points by y0man, can you make height increase stats pls? Maybe just Hp or just attack. There's no advantage in increasing height other than making opponent's Stomp deal less damage because the size difference is smaller. And making your Stomp deal more damage to smaller enemies but as y0man has said, "the 2nd boss starts at 12 meters", is absurd because it's too pricey to increase height.
