Seems my edits in the other thread got me auto-banned. While I wait for admin to unblock that account...

I've gotten as far as the D6 room with the horseheads and it's admitidly hard to tell when it has/has not bounced off the wall. I'll continue onto the D7 room where it's easier to test but this has taken several hours to get to this point so I'm calling it a night. Based on tests, I'm currently at "it looks like the bounce count works" but I'd like to show something definitive like a video with at least a 10-retry consistency which is very hard to do in D6 given the narrowness of the room and the rnd movements of the heads when thrown. Will post again tomorrow.
