I was never good enough to finish Black Tiger, but could usually get to the end of level 7 on one credit, once I figured out that big diagonal jump. As far as Black Dragon, had a really good game going today, then blew it with 2 lives on level 6 (once jumping by accident and landing on the spikes, the other getting magic confused or whatever it was, and didn't have any potions left, and died...would have easily broken 800K if I hadn't.) My first 3 deaths were from time running out (it was being really stingy with the hour glasses), so I used it to take advantage of some extra scoring on the next life. Wasn't as high as my previous though, ended with about 735K.
