Ah yes, because games cannot be hybrids. If you have RPG mechanics, your game cannot have action combat. This is flawless logic. /s
Anyway it's easy to see how wrong you are. Metroidvanias are not defined by their combat systems or their RPG mechanics (or lack thereof), they are defined by their
world structure and level design.
Not only does Blasphemous not even have any stamina-based combat nor much of anything else making it Souls-like beyond some superficial "influence" (much like, say, Hollow Knight -- which is what the poster asked recommendations for!), in both S&S and Blasphemous, you have a non-linear, platforming side-scroller where you backtrack with traversal upgrades to access new areas. Calling them Metroidvanias is not incorrect, so please stop derailing this thread.
I'd assume all versions run fine since it's not a very demanding game, so it'd be whichever you prefer (e.g. Switch if you want portability, PC if not, etc). It was free on EGS a while back so you might have a copy of it for PC already.
