The birthing boss thing is annoying as hell. I've been flapping here for like 10 minutes. Reflecting most shots doesn't hit anything because the boss just moves out of the way. Very few have been timed right to hit the boss in the face. It really sucks having it be totally up to luck as to whether the boss pops out a shot at the right timing to hit.
And I guess hitting the boss in the face is even the goal since it makes the expression change, but honestly I have no idea. Since there's no health bar or anything, it's hard to tell if I'm actually making progress or how much more I have to do. It's important that the game gives feedback to the player than they're even doing to right thing and not just wasting their time entirely.
