I got to play this at IndieCade last year, and the live-action version at Come Out and Play in the Mission District of San Francisco. It's a ton of fun and highly recommended :)
EDIT: if you want to play some cool live-action / physical / playground games the come out and play festival is happening in a few weeks in SF http://comeoutandplaysf.org/
