Humble Bundle first raised funds for World Land Trust (WLT) through the launch of Amanita Design’s game: Botanicula which is a point'n'click exploration game created by Jára Plachý and Amanita Design. The game centres around five friends - little tree creatures who set out for a journey to save the last seed from their home tree which is infested by evil parasites. The original soundtrack and sound effects are created by Czech alternative band DVA.
Release of Botanicula was on 19 April, 2012 and it ran for two weeks.Thanks to everyone Botanicula has saved 1466 acres of rainforest in two weeks! http://amanita-design.net/games/botanicula.html
Since then, Humble Bundle has continued to support WLT through payments to play other video games. The customer decides how much they want to pay for the game and how they want their payments split between the developer, the featured charity and Humble Bundle.
In December 2014, Humble Bundle announced that it had donated an incredible US$50million to charity. WLT was featured in the video released to mark the occasion.
