Thank you for the kind words! I can agree, the boss's health probably should have been lowered a bit. It's all controlled by one variable though, so that can be changed up.
Funny enough, we found out after the fact that punching continuously is actually faster than walking! And the acceleration was mostly a holdover from one of my past projects, back when I was trying to make the character a little 'heavier'. I'll definitely increase the movement speed and make the acceleration much faster for any future updates!
