In 2010 a little known indie game won the Independent Games Festival Grand Prize and award for Excellence in Design. That game was the product of 15 weeks of work by one person.
Since those days, Monaco has continued in development and -- 3 years later -- is available for Steam and XBLA (purchase at www.monacoismine.com).
But that original 15-week prototype had a magic of it's own. This freeware download is that. This is the game that won the 2010 IGF.
