The Reddit community of Outer Wilds maintains an extremely comprehensive list of recommendations, in the style of "if you liked this aspect of the game, try these other games":

I can vouch for Outer Wilds and Tunic being masterpieces, with Blue Prince getting a B+ from me.

Tunic's true ending is unfairly difficult to find. Fun, and obviously attainable, but unfair.

It asks for a very different skill level than Outer Wilds, for sure.

On the other hand, it gets extra points for the in-game manual booklet. The mechanics, the metaphor, and the gorgeous execution should be required material in game design classes.
