It does look interesting, but I'm embarrassed to say (despite the extra key) that it has been sitting on my Steam backlog for a while.

Humble is the best, I've even stopped getting things on the Steam sales! I have a subscription to the monthly bundle, and combined with my existing steam account leads to a few extra keys that have been building up over the past couple of years. Steemit seems like a nice community, so I thought why not give them away here!
