Odallus: The Dark Call comes out next March, and it's a 2D Metroidvania that is heavily inspired by Castlevania. I contributed to their Indiegogo campaign and have beta access. They've released the first level to those who contributed, and the first stage is basically one huge homage to Dracula X's first stage. Also it's really good on its own terms.
Whoah, I had no idea about this Odallus game. Thank you
