Great game, great music.
key appears AFTER the scene where everyone goes to bed, so its only at night
just so you dont wander through town looking for it and rather look for useful items in the barrels and vases. that saves you some time I hope.
I like the fct the main guy fences and parries like a swashbuclker.
I am miffed I found out about the side quest at the silo after i had finishe dthe game :( guess I gotta play again
