I feel like this game (and series you've done) really shows that simple with style goes a longer way than something really complex. You go a really long ways with simple stick figures, and the hand boss is really solid in a way that gives good Master Hand vibes. Tough fight but fair, with all the attacks being avoidable. Also the point where the board gets cracked by the hand is just so dope. I'd agree with other people that a health bar for the boss would help, cause it's hard to not know how close you are to winning.
