Rain World. You are a little slugcat in a hostile ecosystem. You can fight but the predators will brutally kill you most of the time so evading combat is often better. The locations you visit are beautiful and it's easy to get lost, and the other creatures keep interacting even if you aren't there
Another different: NaissanceE. You explore incredible vast locations in a lonely monochromatic world. It's a mix of puzzle with platformer that will make you feel really small with structures that appear to repeat to the infinity. It's free on Steam.
Sometimes it can feel that way, but try to keep pushing if you can. It's a very rewarding experience and left me with good memories.
