I can give so many but you'll have to narrow down your preferences a bit ^^
I've recently been playing Remnant 2, Songs of Syx, Age of Darkness, dotAGE, Helldivers, Valheim, Against the Storm... all really impressive and amazing games made by (relatively) small studios or AA developers with a passion for games. If you're completely new to the indie scene you probably can't go wrong with Hades, Hollow Knight, Stardew Valley, Terraria
Hero's Hour is a pixel art game that's about building an army. Really solid indie game! Also a fan of Revita, it's a roguelike but done very well and is mostly unique.
