I was playing this yesterday and wondering about why it is slow. My theory is that programmers were concerned about not being about to see the character clearly due to ghosting and the lack of screen light, so the game was designed to favor better visibility for the character sprite over better movement. This was an early gameboy game, so there wasn't actually a lot of resources out there on how to use gameboy hardware.
I've never found evidence to support this. For some reason, when people get a chance to talk to Masato Maegawa, they never ask about Castlevania Adventure for some reason /s
