I appreciate the NES graphics, the remix of the soundtrack, and Bloodborne being one of my favorite games. However I found the controls not very intuitive; For example you could've easily routed the standard awd as movement jump and even including s for jumping down to a lower floor for instance. There's no reason for w+k to be the shoot control when they could've remained separate buttons. With criticisms out of the way have you considered hunter tools available similar to classic Castlevania power-ups? Because ultimately that's the closest game you'd be approaching with this style of gameplay. Of course you could also pump up the graphics and bring it closer to a metroidvania which is admittedly over played but still enjoyable.
