A great game and I've spent quite a lot of time here but I still don't know how to get some of the achievements. Why aren't they described in game? And I'm sure I saw once some guide to it but now I can't find it anywhere. How am I supposed to get them if I don't know what should I do to get them? And, as I remember "Displacement" is about scrolling up or down for some time but I did it like for 15 min and nothing so what is the exact time or what else should be done to get it?
