Hello, this looks like a really cool game, but it would be really helpful if there was some kind of tutorial, because I am unable to get past the first talk with the ghost. After he says "Quick, the key in her clothes" (idk why her, because the person in armour looked like man) i go to his armour and the ghost says something like i don't need it, that it would just make noise. I am unable to interact with anything else, so I'm assuming that i have to use some kind of skill?
