Beautifully art-directed, responsive and fun, this game finds me playing it way too much. And it's not just a sandbox: there are oodles of quests, interesting characters and bikes to unlock along the way.
It's free-to-play, and you can grab it from Google Play and the iOS App Store
See Michael, a passionate collector of artifacts and designer of unique puzzles, at Boing Boing's three-day extravaganza, the Weekend of Wonder, running Sept. 18-20. A weekend of workshops, tech demons and wild performances, there'll be plenty of fun surprises!
