While it is indeed an Akumajou Dracula ripoff, it still looks pretty solid. Could be worse
I might disagree. Which is weird as I'm one of I'm assuming very few people that would think "I might go back to play the NES Game, 8 eyes, someday". I know it's hard to describe how a game plays compared to some other things, but this game makes such annoying, stupid mistakes and utterly fails to capture the level design of Castlevania. It's way too cheap and needlessly confusing.
It's actually pretty weird. My love of Castlevania is why I found this game to be cool but that also exposes the game's issues so much...
But the NES has certainly had much, MUCH worse.
