Yeah, I wish we had been able to explain the heat mechanic better and the boss was unfortunately bugged as you discovered. The idea was that as you become burnt you sorta crumble and fall apart more easily? But completely agree it’s not explained at all in game and my explanations here on the rating page probably don’t do enough to signpost it. If we get to develop this further a tutorial would for sure be high on the list of things to do! Thanks for playing and leaving such good feedback :)
