I mostly wanted to mention how it's inspired by that a bit so no one would think I was trying to make it look like something actually out of Castlevania (as I did with visual style of Castle Murderstein and Duke Murderem to Wolfenstein 3D and Duke Nukem 3D respectively) nor trying to make a replica of a location in any Castlevania games. I didn't want any confusion on it. I'm glad you got the reference at least.

We know this Castlevania! Do not tell us!
