We still consider doing a more dynamic camera for bosses, but it really is a case by case thing. Some bosses will be smaller but will move a lot, other will be huge and fill the entire screen so we'll really have to try different things for each one
Yeah, no "one size fits all" with this type of thing, and gameplay is definitely the priority. Plus, there are plenty of ways to get that same intensity without applying advanced camera work, by using tools like screen shake, lighting, music, etc. No doubt you guys will make your game the best it can be, keep up the good work.
