To be clear - Outer Wilds is another design system where everything is unlocked at the beginning, but obfuscated from the player until they play through long enough to learn the mechanics. Same concept, just applied to various game mechanics, but not movement mechanics.
I think that one of the biggest things that Celeste has going for it is its movement mechanics. It's this brilliant system where you are given all of the powers you need at the beginning but aren't taught how to use them until completing the game (i think a lot of the mechanics are actually revealed in the B and C sides). This also gives Celeste some killer replay-ability - there's nothing better than going back to early stages and using learned movement tech to break intended solutions. I think I could be convinced to categorize that as a bit of a revolution of game design.
This is also something that Outer Wilds did really well imo.
