It says it all in the title really, but it's great news! Ed Key and David Kanaga's game Proteus will be available on Steam and through the game's website. Priced at $7.50, which makes it around £5, its a smashing deal as well! From what I've played of the game it's beautiful and very exciting [read my thoughts about it here] and I can't wait to play it as a finished piece. Proteus ahoy!
