After you escape from the Scarlet Room in episode one, “something hit your head hard, and after that… only fragments of memory! Your head hurts a lot, like all your body. But at the same time, you can’t feel your body: you can’t touch anything and feel like flying! You are now in a room in which everything is red, and there is a body lying on a bed…”
According to the stats on the game’s page, The Scarlet Room II is quite challenging: at the time of writing, only a few players (less than 0.3%) have succeeded to escape from this room!
