IGF 2013 Excellence in Design nominee Starseed Pilgrim was released on Steam today (Steam releases were offered to all the nominees this year). This unassuming and enigmatic puzzle platformer has become a hit with a number of indie game developers, including Bennett Foddy (QWOP) and Braid creator Jonathan Blow, who called it his game of the year for 2012. Since so much of the enjoyment from Starseed comes from figuring out how the game works, it’s hard to describe even the basic goals without spoiling it. If that sounds fun to you in and of itself, you should probably give it a go.
