Need a partner for all missions gold result achievements.

I'm sure these questions have been asked many times before, and I'm sorry for that. Did some googling but got vague answers. 1. Can this game be played single player? Or would I struggle? 2. Do both players have to own the game? Or is there something akin to a friend pass that allows friends to play this with me, without them having to buy the game also?...

Some boxes just cannot be moved. We tried everything with no luck :( Restarting the level changes the layout, but it still occurs the issue on the second delivery. Please help. We cannot skip the level either :(

Me and my husband got Keywe and it’s DLC’s but when we try to create a room and input the code, it says “Can not join room”, Anybody else having this problem or have found a solution?! Please help, this is very frustrating!
