Hey! thanks a lot! :)
Chapter 2 will be a separate game, it will be as long as chapter 1 so it seems right to do it that way ^^
As for the translation, I know that a lot of groups make translations in Spanish and Portuguese, I'll see if there is a good translation that is proposed and I will ask permission to add it in game :)
As for the linux version, I'll see, I haven't had time to look into it yet.
