What's your favorite metroidvania ability?
Warning, potential spoiler for games you might want to play
Mine is flash-shift from Metroid dread. It's a quick dash to the left or right. I just love how snappy and smooth it is, plus the sound is very satisfying
Mine is Bash from Ori and the Blind Forest. Easily the most versatile movement mechanic that doubles as an offensive/defensive ability in combat (also just looks cool kicking projectiles back at enemies).
Not game specific but for some reason I just love double jumps in any game.
