Its not Castlevania but I think its very similar to it!
You're using Game Maker? You use tiles or import a pre-made map in the game, after doing one? What about these old but gold TV-like borders and scanlines, you added it for cosmetics or it appears in the game?
I'm happy to see that this thread is about your project, with this title I thought someone would mention that Kickstarter from last year that was C&D for obvious reasons.
