Just had to respond since Metroidvanias are one of my favorite genres.
Naturally, Symphony of the Night is among my favorite games. In that vein, I’d also recommend any of the GBA/DS Castlevania games: Circle of the Moon, Harmony of Dissonance, Aria of Sorrow, Dawn of Sorrow, Portrait of Ruin, and Order of Ecclesia. Plus there’s Metroid Zero Mission and Metroid Fusion.
As others have pointed out, Bloodstained is excellent. However, I’m a major outlier when I say I’m NOT a fan of Hollow Knight. It’s ok I guess, but I just got bored by it, plus it’s really difficult. On the other side of that, the only Shantae game I’ve played is Risky’s Revenge, which was fun but insanely easy. I really want to play Seven Sirens.
The game I want to add: Blasphemous.
It took me a bit to warm up to it, but it is EXCELLENT. Amazing pixel graphics, tough-but-fair bosses, memorably bleak setting, and great soundtrack. I liked it so much that when I finished it for the first time I immediately began another playthrough.
