I think the Hunter might be bugged. I noticed that when firing the rockets, i take some damage. With the golden style, i can last a bit longer before dying, but without it, that damage is enough to instantly kill me, even with armor maxed out.
This is only present in the remastered version of the game (the one currently playable on the web & purchasable via itch.io); the mobile & original versions do not have this bug as far as I can tell.
