Running around the city in a pack + night time + stupid movements = v. exhilarating and fun.
It works like this. There are cryptoids – special creatures – with special characteristics. You have to run around to find them and once you find one, you have to act like it in order to not scare it away. Once you befriend a cryptoid you have your photo taken with it and the person with the most photos wins.
It could work better – there were too many creatures with too many characteristics and we were asked to memorise an impossible amount of stuff. That didn't work.
But properly running around a city at night in a pack, doing silly movements and having crazy rules about how to interact with space, eg, swing around every lamp post when you see a ninja rabbit or whatever – was great. Want more. Maybe parkour next?
