Botanicula is a point-and-click adventure game developed by Amanita Design. I'm not even convinced it's a game. It's definitely point and click, and it might be an adventure, but game I am not convinced about. You click on random things until something happens, and then you ask 'was that actually what I wanted to happen?' before realizing that no, you still don't know what the point of all this even is.

On a bright note, wikipedia says that Botanicula is helping the World Land Trust to protect hundreds of acres of rainforest.
