I have decided to cancel the giveaway.
Sorry.
Humble Bundle clearly says not to give away your spare keys.
I am respecting their wishes.
I wouldn't care if giving away a spare key was a opinion of some people, but the fact that humble bundle says directly not to kinda seals the deal.
Next time I'll research this giveaway thing more thoroughly before getting people's hopes up.
Again, sorry.

Not in, as I already have a superfluous Capsized key myself, but +1 for the giveaway.

Also to those who might be considering ranting on about "poor developers", "licence breaches" and the like, bear this in mind:

We had a small minority here posting in every giveaway and ranting on about how Steam keys were being given away from bundles. I know that Humble Bundle would rather that you didn't give the Steam keys away, but ultimately, you've bought the game twice and should have the right to do with your second copy as you please.

Capsized looks interesting. Count me in.

Yeah, I'm in.

Thanks for the giveaway! No-nonsense, 24-hour; I like that :) Count me in!

I'm in..

Thank you!

In, thanks!

I suppose. I mainly got the bundle for awesomenauts.

in, thanks for the giveaway.

Thanks, in.

I'm in. Thanks.

I'm in, Thanks

Yes, you should only have to obey rules you think are fair. Or, in other words, you should be allowed to do as you damn well please, and screw the rules.
