Not a platformer but highly recommend Castle crashers

steamworld dig 2

I hope i can help. I know the Problems myself. While Super Meatboy is fun it is tough as nails, similar to alot of other Plattform games, what truly are made to torture People.

I sorted my games for "D Plattformer and here are some Short, and not to difficult games.
I Love the trine series (even the third, which is 3D and the worst in the series).
highly recommend picking up Trine 1 and Trine 2. I don't have an Excact Time Estimate, the difficulty is not very high (mostly Colelctibles).

While Celeste IS very difficult, it got a very nice feature (a cheat menu) if you don't mind to use cheats even people that are not very good will be able to complete this game (people like me).

Recently i finished the Purring Quest, it's a 2hour ish 2 D Plattformer where you navigate a cat, just 5 level and basicly Collecible Hunting (i liked it).

Something slightly more Challenging, but also short is 1 Screen Platformer, which i would rate at 5/10 maybe 6/10 to 100%, it's rather short and i enjoy that this basicly only is one long level.

If you count Autorunner into the mix i would also Recommend BitTrip Runner 2 and Return Of The Zombie King. BitTrip Runner 2 was a really nice Autorunner, but can take 20+ Hours to complete (if you take it slow), But it's not that difficult.
Return Of The Zombie King is shorter but got some Twists. This game got an upgrade System, you collect Coins and can upgrade your Character and go further in the next run, some "missable" Achievements, but you can look those up easily (basicly avoid some of the upgrades while completing the game). Got some Game Boy charm and i liked it.

Hope This helps.

Cheers

Thank you for putting in the time and effort for this reply! There are some times where I am up for a trying challenge but not in the mood for that currently. I have 100% completed SMB and Celeste but I will look into your other recommendations!

Im gonna suggest The Adventure Pals! Its not as long as you are asking but its very chill and hilarious and isnt too hard! I really enjoyed it and recommend.
