The daughter burst into my office the other day "Daddy, the multiplayer has been released!"
"For what"
"The second goose!"
"Oh great"
"Can we play it?"
"Not today"

A day (or two?) later:
"Daddy can we play goose game together?"
"Sure"

We decided it would be the first game we streamed on Twitch (as the daughter has been commentating all her games recently anyway). Couldn't get the microphone working and the capture card was having issues with the sound, but we had fun playing it anyway.

Started with a new game and had it done in about 1.5 hours (or less). The puzzles aren't that much easier with two players as it confines you into a fairly small window and some parts can become a touch frustrating particularly the pub where it's very easy for the man to shoo one of the goose out which forces the other goose to come back close to the entrance to let the first goose back in.

But they can also help each other out by picking up heavy large items together and the final part of the game is slightly easier with the other goose running distraction.

And yet, again, you know if you want to play this game just by looking at it, I'm not sure that co-op will change your mind.
