Here's a list of collective updates to the Humble Indie Bundle, in case you haven't visited it after the sale (chronologically, too):
- Download page updated to reflect source code release status
- Samorost 2 soundtrack download added
- Gish for Mac updated (yet again)
- Aquaria and Gish are now open source
The item that I want to put a bit of emphasis on is the last one. Now all of the developers that vowed to go open source have released their source code. I can't wait till I start digging through Aquaria (which should be soon, extracting the code right now).
