I am happy to announce that Hadean Lands can now be purchased directly from the Humble Store. (It's currently listed under New Releases, though of course it will scroll off that page pretty soon.)
This is the same version that's been available all along. (No, I have not done a bug-fix release. I know, it's getting to be time...)
The Humble Store is fixed-price, not pay-what-you-want. The win is that 10% of proceeds go to charity.
You can still buy HL through the pay-what-you-want widgets on my web site. It's still in the Adventure Gamers Store. And of course the iOS version is still available from Apple.
(Have you voted for Hadean Lands on Steam Greenlight?)
