I really tought that the gas periodically coming out in the wents would lead to a bad end because of how they were split up and such it just kinda made sense so... i kinda dodged them for a while (until i got tired off it and just kinda tried to see what it did... tough that did take a while as i was trying to get the heart key to the door... never did succeed in that a glue dog or whatever ya call it jumped me in the hallway after the first lock... i tought it was only there if you were already turned as i always got jumped there when i was and i gave up getting there untransformed tough i couldnt do anything in there while transformed unless i missed something)
Once again im rambling
