Unintentional floor drop occurred shortly after finishing the Berkeley mansion during an attempt to kill an enemy gone wrong, but as it did me much more harm than good (in health and time) I figured it would probably be alright. Was a very sloppy early game even by my standards and the route was altered to adapt to my personal skill level, but all in all considering where I am at I was pleased with the results. Whether or not I 100% kept to the rules is unknown, but I sure tried!
