If you are looking for fun co-op game checkout Peak

I played it as per friend suggestion. It's simple yet very funny! We spent 4 hours trying the game and finished our first run in under 2 hours with a lot of deaths...

Recommend it!

My friends and I have been playing this since the recent launch. It's a lot of fun! The map rotates daily so it's a fresh challenge for you to explore every day. I'd recommend starting on the easy "tenderfoot" mode to get a hang of things first.
