i got the chest. you can destroy the upper-left thing hiding the sigil with the whip & some awkward jumps as i discovered by accident. then destroy the pot with the flare gun, then use the gale fibula in the room to the right and do some really precise jumps.... it was cool but u just get a damn orb
also hmm i dont even know how to get through the corridor of blood because at one point it rotates vertically and you have to climb up to reach the next door
i think there was a hint somewhere implying [sp]you can force it to rotate yourself somehow[/sp] but i havent figured out how..... if u know dont tell me
