By the way. From the technical point of view, cross-platform development on PC (Win/Mac/Linux) is extremely easy if you use the right combination of tools and libraries. Although, this requres a lot of research and adaptation from the programmer. These days if you're creating a small indie game with an in-house game engine there is no reason to be tied to a certain platform unless you have _very_ specific requirements. PC is infact very easy compared to the stuff presented in phones and consoles...
I don't know the tools the developers have used to create this game and it is totally possible we will never see a Linux port. Hopefully this is not the case.
