I must say, this game requires you to play with your friends to be easier. You might struggle in some parts if you play solo.

This game includes Remote Play Together - which is nice -, sadly both can't play with a keyboard, though, one of us has to use a controller to be able to play remotely (this is something that Steam could change one day, maybe).

The game includes unlockable hats, characters, weapons, etc., just by completing challenges and some levels.
