I wanted to sleep, but I noticed this game still has no review with a positive score. Overall has a two-star rating sooooooo it's not entirely hateable. In fact I found it mostly entertaining and, despite not having played a lot of the Game Boy library yet, I'd say this one, Kid Dracula, and even with its flaws, Belmont's Revenge (CV Legends DOES NOT exist), all Castlevania Games, could be the highlights of the system.
This Belmont may be the slowest in the family, yeah, but thanks to that you don't even have to worry to go backwards. It's a slow but safe journey. With precise platforming here and there, so watch your feet, literally.

Best Castlevania artwork cover of the series too.

How can the tutorial be the highlight?

The game that showed me that sometimes, in some cases there's a way, not always spottable at first sight but framed inside the gameplay, that can transform a game into something different entirely. And better.

Even with this rating, it still has one of the best fights I've experienced in any game: the second to last. It's engaging to learn and feels rewarding to beat it. The last one is entertaining to beat too, but it's more puzzled than the one before.
