Boomershooter with similar vibe and setting as Castlevania (possible Doom mod?) – From /r/BoomerShooters

Hello,

Last year I came across a boomershooter game (thru YouTube) that I want to track down again (as I purged my YT history). I remember that it had 2.5D graphics (hence why my assumption of this possibly being a Doom wad) and the thing that struck me the most, was It’s 8-bit soundtrack, which sounded like it belonged in a Castlevania game.
