Pseudoregalia has the same endless space for skill expression in the movement - the platforming is deeply satisfying and scratched a very similar itch for me!

As others mentioned, A Hat In Time is delightful and has similar room for skill expression

Celeste is 2d but the single best platforming game I have ever played. Its movement system is so, so satisfying and deep

You might enjoy Ratchet and Clank: Rift Apart - its a ton of fun, but a slight sideways shift in genre

I also found Cavern of Dreams pretty delightful as a cute 3d mascot platformer

I would be failing you if I didn't mention A Short Hike - it's short, as its name suggests, but it is an absolute blast

The second I saw someone mention A Hat In Time my mind sprung to thinking Yooka-Laylee as a viable option. It's made by a studio founded by ex-RAR employees, IIRC, and has been a game I've played on and off but find a lot of fun. Especially from an exploration standpoint.

Game is basically running through a giant hub, going from level to level, collecting magic book pages, all in order to get back a book that was stolen from one of the main characters. Levels are pretty big too, with expansions as well. Has a Banjo Kazooie vibe, from what I know about that franchise.

There's also a switch port, assuming you don't feel like spending $19.99 on Steam for the original ( 7.48GB space required ) or $29.99 for the remaster ( 25.96GB space required )

Astro Bot on PS5 and Sackboy for PC and PS5

if it's the switch version of 3D World you're emulating, have you tried Bowser's Fury mode? imo 3D World is neat but Bowser's Fury is absolutely phenomenal

Penny's Big Breakaway is on Steam and it has movement options very similar to Oddessy paired with Sonic-style rolling gameplay. I think the bosses are a noticable weak point but the levels are fantastic. if you like the momentum stuff, Spark the Electric Jester 2 (cutscenes but you can skip 'em) and 3 and Rollin' Rascal (early access) are excellent as well

+1 for Kirby and the Forgotten World, magnificent game. if you feel particularly brave, the much maligned Balan Wonderworld is similar but with an emphasis on revisiting old levels with new powers ala LEGO Star Wars. i enjoyed it but most people did not so maybe save this one for a steep sale and a rainy day

I think the most natural candidates would be Super Mario Galaxy 1 and 2.

what about the other hat based platformer: "a hat in time" ? lots of fun.

I’ve heard that new Donkey Kong game is just Donkey Kong Mario Odyssey essentially.

Odyssey is up there as one of my fav experiences of all time. Possibly Kirby and the Forgotten Land. Galaxy scratched the itch like someone else suggested. For some reason I couldn't get into 2 but I know it's considered as better. Quite different but Celeste controls so well it kind of feels similar in that way.

I'm going to go through some of the replies too. Lovelovelove Odyssey.

Edit: Perhaps with trying Luigi's Mansion 3. Not a platformer but very fun.

Seconding A Hat in Time. It's probably the closest platformer to Mario Odyssey that isn't Mario. The last DLC (Nyakuza Metro) is especially worth your time.

astrobot!!! as much as I love mario and nintendo I gotta say I might like it even more than odyssey.

if you're just on switch tho splatoon 3 might be perfect, it's not only a platformer ofc but the freedom in movement and the level design are great
