Ion Fury i have great fun with this problem is i tend to start games straight on hardest difficulty ;p so havent finished it yet

Murder House if you're into retro survival horror. (Shorter game, about 2-3 hours)

Two or three days ago was released indie game Wilma's dreams. Fighting 2D game with bichone frise werewolf. Enough fun for 3.3€.

Celeste
Axiom Verge

Forgot to mention. I've played Wargroove sometime ago, highly reminded me Advance Wars from GBA. Some like that or inspirations from Final Fantasy and many others as new retro i could love.

Odallus The Dark Call is fantastic :)

I liked Hargrave. It's free too.

Most of you says Odallus... I will keep in mind on next sales.

Recomend me more, because as 31 years old gamer, spended alot of time as kiddo on platformers, or some other titles on NES.

Cathedral is great, its similar to Shovel Knight

I could advice KUNAI, quite similar to The Messenger, a quite good 2 plateform with retro graphics
That was at 1 euros/$ on fanatical bundle : https://www.steamgifts.com/discussion/sxtTs/fanatical-build-your-own-blazing-bundle , unfortunately this game got removed from this bundle

In general, I would recommend metroidvanias. The genre as a whole is so heavily influenced by Super Metroid and Castlevania: Symphony of the Night that most games have a bit of a retro feel. I think that you primarily named the games that I would instantly recommend, but here are the ones I'd personally shoutout:

Katana ZERO - It is a very interesting game. It has individual levels that are somehow a combination of a puzzle game and an action-platformer. The game has decent replayability with time trials and harder difficulties. The story does have a lot of heavy stuff including war, drug use, and PTSD, so it can be a bit hard for some I'd imagine.

Panzer Paladin - A game that I mostly enjoyed. It's a pretty fun and interesting take on action-platformers. Some of the later bosses are a bit rough and the checkpoint system feels reminiscent of the overly-punishing systems in the older era. It feels a bit similar to Mega Man if I had to compare. Fun game overall that I would recommend.

Momodora: Reverie Under The Moonlight - Momodora: RUTM is one of my absolute all-time favorite metroidvanias. It is a bit on the short side and the controls take a little bit to get familiar with, but it is such a great game overall. I absolutely adored the game and would highly recommend it to any fan of metroidvanias

For some reason I enjoy more this kind of game that the latest AAA
Here's a few, just to start

Immediately rushed to recommend The Messenger and CrossCode, but looks like you know of both already. :D

Outside of those two with their obvious inspirations, I'm not really sure what makes a game retro, to be honest... So I'm gonna recommend some games and you'll need to decide if they're retro or not... ^_^'

Wings of Vi - Probably the most likely one to qualify. I should mention thought that it falls squarely into "Platformer Hell" territory. ;D

Dustforce - A very interesting (and challenging) precision platformer.

Intrusion 2 - Action platformer with very unique object physics. Short and sweet.

Robbie Swifthand and the Orb of Mysteries - Non-action platformer. Even has that 90s B-Movie styled title. XD

All the Shantae games but especially Shantae and the Pirate's Curse.

Rabi-Ribi - Probably the one I least expect anyone to try out, but I have to recommend Rabi-Ribi. It's a mix of Metroidvania (with exceptional metroidvania elements), platformer and Bullet Hell (mostly the bosses), so it's tough and quite complex when you get into it, but it's so very good. (And cute. Can't forget cure.)

That's all I got for now, off the top of my head. ^_^'

let me add "pixel art side scrolling" missing from the great comments, (sad RTS and management retro noise)

Sonic Mania - actual new game of a retro game
Blasphemous - inquisition jokes aside, absolute gem
Narita Boy - extreme retro?

Thanks guys for your recomendations, i know which ones i gonna get on next sales. But if you got even more recomendations, say it and i will look on them. :)

Valfaris.
Odallus.
Blazing Chrome.
Cross Code.

And no one mentioned.

River City Girls.

Like, games with retro pixel graphics specifically? Because there are also e.g. Nintendo 64-style retro titles as well. It might help to be a little more specific!

Anyways, check out La-Mulana for something seriously oldschool and Nintendo hard.

Jimmy and the Pulsating Mass is amazing if you want something like Earthbound.

Anodyne and The Elementalist for Zelda-alikes, with the former being a surreal/horror take on the whole thing.

The rest of this is just stuff that looks cool that I haven't played yet:
Creepy Castle
1001 Spikes
Artifact Adventure Gaiden Gameboy style!
Micro Mages
