Thanks for the feedback. The boss can also be slashed like a normal enemy, but I didn’t add an animation for that, so it’s understandable that no one noticed it. Bullets firing at a fixed rate was an intentional design choice, to prevent hoarding them through waves and to encourage aggressively approaching the boss. (resetting the bullet count every wave was another solution but I felt it was confusing for players who didn’t know)
My bad for not adding enough cues to show players this.
