I really like the boss intro cutscene and the hatch shader that you used! The hit effect that plays when you damage the boss is really nice too. Great combo of sound, hitstun, and visual effect!
Even though I really like the hatch shader, I think you might want to consider turning down the shadows a little bit. It can make the tutorial signs hard to read. I love the effect, just might need to be dialed back a little.
Awesome job!
