Now for some Retro stuff:
logy
Rockin' Katz
A good Platformer about a cat with those punch glove guns that lets him bounce from walls, spin from ledges and grab projectiles, hitboxes are kinda funky but still enjoyable
The Rocket Knight Trilogy, hard but fair games, basically they friggin gave Sonic a Sword and a jetpack, you can't get coller than that (maybe with guns and a bike

)
Of all the Classicvanias, the one i reccomend to a newcomer the most is Super Castlevania IV, by far the easier of the saga before the Metroidvania genre settled in the franchise, you can still lose if you get cocky though
