Sundered is a cool 2D metroidvania / action rogue lite blend.
Absolutely gorgeous artstyle, unique concept…
Loop Hero is another rogue lite, that has a bit more of a management feel to it. The hero traverses the loop (the level) automatically - you just get to change their equipment and the environment. It’s a cool balancing act between making a tough level with synergetic enemy types/tiles and making sure your hero survives.
Hollow Knight - if you like metroidvanias you probably know that one. It’s incredibly popular! amazing game.
Dead Cells - same basically :) 50% off on steam right now!
Edit: Seems like you’re looking for retro/emulation stuff mostly? I might be misunderstanding your comments.
These recommendation all have Switch and PC versions. No clue how well they would run on yuzu
