I finished this game last year with my son. Very fun co-op game. Great for non-gamers or beginners, because the difficulty is pretty low but it's still fun because of the multitude of creative mechanics and fun/smooth gameplay. It won game of the year 2021.

The same dev of It Takes Two just released Split Fiction and I'm also in the process of playing through it with my son. We are about 5hrs into the game. Also very fun! I recommend both games if you have someone to play it with. Great co-op game. Also, an awesome thing about Split Fiction is you can do couch co-op or online co-op, and with online co-op, only one of you has to own the game for the both of you to play.

Lovers in a Dangerous Spacetime is another great co-op game I would recommend. And of course, there's Overcooked and Overcooked 2, both are great couch co-op games that can get you high-fiving one another at one moment then start screaming at one another the next moment.
