I have a spare copy of this game I'm willing to pass along. It's one of my favourite games, and one of the best games of the year, a 2D platformer game, but not in the traditional sense of a platform game.
The gameplay is somewhat similar to Minecraft, in that you mine and build various common to rare materials, craft them together, and plonk them down to make houses and structures or craft them into weapons, armour, furniture, and other potpourri. As you get stronger gear, you are able to survive against tougher monsters further out and further down, and explore more dangerous regions for even better and rarer items.
The game is a sandbox, casual-friendly, works on low-end machines just fine, and has tons of content and free content updates every month or two. The world map is randomly generated each time you start a new game, though you can share different maps (and even items) between different characters of yours, and it works very well in multiplayer too - you can use a character or map from single-player, or both, to play with friends if you desire.
The game ONLY activates on Steam - there is no stand-alone version yet. So you must have Steam (it's a free digital distribution platform) to activate this product key. Current retail value is $9.99.
Sorry I can't set a GIN price yet - don't have that badge yet - but if it somehow gets to 1k I'll give the winner a bonus choice of a full Humble Bundle 3 unredeemed gift key (including the five HB2 games), Tidalis or Freedom Force. Else they'll probably show up in subsequent auctions. Except that HB3, too many of those floating around. :)
Short duration so at least whoever wins it can get one evening of playtime out of it before this long weekend is over. :) I will need your e-mail address to send you the gift to redeem on Steam. Happy Labo(u)r Day!
