I'm not sure what happened. Other people seem to have been able to play but when I played I ran around in the desert for a little while and wasn't able to see any blue thing. I was unsure what I was supposed to do at that point :(
hmm that's weird there was not a little light blue thing like in the gif's? It should be straight in front of you when you first start in the ground. When you walk up to it a chat bubble will pop up and you click through that to start.
