Preorder key page retired

You no longer need a preorder (SPF) key.

The Secret Preorder Forum is open to everyone now, so you can read it directly, and the old alpha download links there work again: original installers up to a181, reconstructed Windows, Mac and Linux builds for a182 through a217, and the build-server zips for a220 through a227 and the betas. Beta b2 comes from Steam's depot history. Still missing are a218 and a219.

Start at the older builds thread or the forum index.

The current release of Overgrowth is available in your Humble Bundle library or on Steam. Questions: contact@wolfire.com.
