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!
