PlateUp is on of my favorites to play with my husband. It's similar to overcooked with roguelike elements.
Chained together is another we've had a lot of fun with. It's simple but satisfying and not too difficult.
It takes two this one is really great, long campaign and lots of competitive minigames. The writing wasn't my favorite but didn't detract from it.
Castle Crashers one of my favorites from my childhood.
Spelunky absolute banger of a platformer, also roguelike, very fun
I'll add more later if you'd like!
