Really funny and cool aesthetic!
I was in a similar boat with the difficulty curve. I wasn't sure how much my clicking the crosshairs was helping me in combat.
I also could not tell if there was any advantage to choosing one limb over another, keeping right limbs on the right side or not.
Your UI is very smooth, so maybe just a bit more information presented would help here.
This is shaping up to be a really cool game, I'm glad you brought it along from Round 1!
