I really enjoy the mortifying feel of finding something you probably shouldn't have. Great execution of this, and I am still far from discovering most of the stuff you crammed in here.
I do wish, however, that along with the other ingame settings, you could add an auto run row (0, 1 off, on). It would make moving around and combing the levels a lot less intensive on the pinky. Might be a weird complaint, but it's hurting. My pinky... Keep it up!
