Bit more feedback: the bomb girls in Metal Underpass send out red projectiles on death, but said projectiles get lost in the also-red blood splatter and are often very hard to see. It took me killing several of them before I finally figured out what I was getting hit by, and even then, there were times where I couldn't see their death-shots even though I knew they were there. Please change the color of those projectiles. Also, minor grammar mistake in Paige's convo (also in Metal Underpass): she says sunlight "aren't" instead of sunlight isn't.
By the way, I did eventually figure out that reserve power-ups get sent to the inventory when you get a third, but to reiterate, my issue is that the boss's kneeling will abruptly send it forward into players if they're whipping the boss, giving them no time to react. Even if I had kept the float/sword combo that I went in with, I still would've taken the cheap hit since the sword is also close-range. Maybe you could have the boss kneel in the other direction, away from the player? It'd fix the cheap hit without you needing to draw new sprites or add that "!" zone.

^like that.
