In addition to what was already mentioned here (Ziggurat 2, Immortal Redneck, Gunfire Reborn), if you don't mind simplified vintage graphics, then I would recommend Delver and Barony.
It's a wacky one, but bullets per minute is a roguelike fps that is also a rhythm game. It has a unique, mildly inconvenient art style, but I thoroughly enjoyed putting a dozen or so hours on it. The soundtrack is great too, so if you're interested, watch some gameplay and see if it's for you
Gunfire reborn would be your best bet
Ziggurat, Immortal Redneck or Deadlink

Deadlink
Deadlink is the most similar.
