Totally relate to that. My experience with videogames is that I loved them growing up, then completely stopped playing them for like a decade after 2D started to be entirely phased out, but now that Indie Games have become a thing, I'm all in on them again (with a few exceptions like FromSoft, Portal, the Shadow of the Colossus guys, and stuff like that).
I'd recommend checking out Into the Breach, Downwell (I've yet to find anything more purely addicting), and Cyber Shadow.
Also, there's a part of me that feels like the boss rush modes of Hollow Knight are better than the actual game. It does the Soulsborne stuff much better than it does the Metroidvania stuff, IMO.
