Sorry for the inconvenience, the Humble Bundle version should be ready tomorrow, we had some technical problem...
If you go through Steam, it will download automatically . You can get a Steam key for Castle Story with your Humble Bundle account, if you go in your Library and click on Castle Story Steam Key and you copy that key in your Steam account (Under Games->Active a product on Steam). A little screenshot to help you. http://screencast.com/t/pAipgSxQ4
