Is someone interested in the Witness? It doesn't have a native Linux port but it does work with wine (although not very good. [users-only]I already have this game from a previous humble bundle and I just got it again from the humble monthly bundle. I will happily give it away as a steam key or the drm-free version on humble bundle. If no one is interested, I can keep a 5$ gift card for the humble store by myself.
So if you want the game, just send me a PM and we'll discuss everything there.[/users-only]
