It's a pity this game doesn't have achievements, while Dead Diary, though older, has them. Do you plan to add some?

I just finished(?) Redrum 2 and the ending was so disappointing was all of this build-up really for the Uncle getting lobotomized, the Doctor cloning himself, and Rose running away from everything? Because that was (as I said before) super disappointing and I'm wondering if I did something wrong in my playthrough or if that's really how it ends. If this is how it ends though, will there be a Redrum 3? ...

Could someone please add an option to change the language of the game? I know the game is available in different languages, like german.
