My friends would come over on weekends and yell at each other at the living room while I convince them that my dad works at Nintendo, just like old times.

On a serious note, this game is a blast to play with friends, especially when it's couch co-op, plenty of satisfactory "high-five moments" to be had. Solo mode is fine, but you'll get less rewards. A note for hunters out there: there are some achievements that can only be obtained by playing multiplayer. So yeah, I guess that's the downside of this game, it kinda begs you to be played on (local-only) multiplayer mode.

Devs, if y'all are reading this, whenever you have the resource, it'd be nice to add a competitive "racing" mode where players can see who gets to the finish line first by giving them a choice between the safe route, and a more efficient but risky approach by using the swinging parkour-esque mechanics in the level design (because I find the level design you guys have made quite impressive). While you're there, mayhaps a sandbox mario-maker-ish level editor would also be nice.

I highly recommend this solid multiplayer game to everyone. It kinda teaches you to tolerate (or not) others' different ways and behavior towards reaching collective goals.
