A new Humble Bundle has launched, celebrating the games of Amanita Design -- including the newcomer, Botanicula. The nature-themed adventure title is the standout of the set, but it includes five games in all for paying above the minimum. Plus, true to the game's message, you can contribute to a conservation charity.

The two-week promotion starts today, and you can purchase your bundle at the official site. Botanicula involves guiding tree creatures to save their home from spider-like villains, and includes a soundtrack by the Czech alternative band DVA. The bundle also includes Machinarium and Samorost 2. If you pay more than the average (currently around $9), you'll also get the Czech film Kooky and the Vectorpark puzzle game Windosill.

As always, games are supported on Windows, Mac, and Linux, with Steam keys available if you pay more than five bucks. Instead of Child's Play, the charity this time can go towards the World Land Trust, a charity that seeks to save threatened habitats.
