Ember Knights is a rogue lite heavily inspired by the gameplay of hades. Supports up to 4 players.

Plate Up is somewhat simmiliar to overcooked, but is more about process optimisation and not about dealing with the oddities of a stage.

Most lego games also offer local coop and are good fun.

30xx is a roguelite with gameplay simmiliar to MegaMan X that can be played by 2 players.

Towerfall Ascension is also worth a look.

Hell Divers is also a great game, but it had sound issues(strange echoes of some enemy sounds) last time i tried.
