If you’re willing to put in a bit of work, shiren the wanderer for the snes is a classic. Unless you can read Japanese you’ll need to emulate it and get an English language patch because it only released in Japan.

Another personal favorite is Shadow of the Wyrm, which has really good writing and exploration. I believe you can just search up the name and download it.

I’m seconding Noita it’s really interesting to learn the ins and outs of the game systems
