So most of that was pretty good, but (despite the theme having the word chaos in it) I have to say that entirely random movement and attack selection coupled with melee only player attacks and contact damage makes for a pretty frustrating bossfight. I got there in the end, but it was luck, not skill. Other than that it was pretty, and also pretty good (though my opinion might be a bit skewed by the fact I figured I could just pacifist run though pretty early on - not sure that was intended?)
Oh, and I very much appreciate the less-than-immediately-lethal spikes.
