PookaMustard: To be honest however, I'm not asking for a Linux version of the game (on GOG) because I personally need it (I'm primarily a Windows user), but because I felt the need to make it stated and clear. Humble Bundle sells the game DRM-free, pure, for Linux users. Why is it not the case here? There's only a Windows and a Mac version but not the Linux version, and that applies only here, and this sadly alienates Linux users or to be Linux users from accessing the Linux version if they bought it on GOG. I only demand that the already finished Linux port gets to be for sale here, nothing more.
