    Loved this year’s challenge! It was a delight to break 🙂

    It took me a comically long time to figure out that all the seemingly random words weren’t so random after all – they do make a phrase that makes sense!

    hehe I actually did it with a team this time! (there were 4 ppl but only one other helped but they were awesome so :D)
    Incredibly fun, would recommend.
