For sure. Though I’ll be honest, I actually prefer lower difficulty games because I like a casual stomp :) I’ve only beaten one level 6 adversary, but half the reason is that I prefer level 3 or less adversaries even when I play the spirit I’ve beaten level 6 adversaries with. Hell, I’ll even play base difficulty a lot when I just want to knock around with other spirits.

Half of the “perfection” for me is that Spirit Island gives you the game you want to play when you want to play it, as long as it’s a cooperative game with spirits murdering civilized invaders :).
