SpaceChem Giveaway

Hello, I decided to post this if there is by any chance somebody that still doesn't know about this..
So PC gamer and Bundle Star made this awesome giveaway, 5 weeks, 5 million keys, every week a different game.
You can get the first game, SpaceChem here for free: http://www.pcgamer.com/2014/06/25/we-have-one-million-spacechem-steam-keys-to-give-away-with-bundle-stars/

The game is really nice, but it's hard... well anyway,have fun! :)
