I was very happy to meet my goal of a 400+mil ALL with Momo in Ver 1.01 today, with a score of 401,002,380.
The last boss is very difficult to score on with Momo due to her weak lard attack, and I just barely scraped through the last phase with a very lucky dodge with no lives or bombs left. Scoring with the lard attack at the end was just enough to push me over the 400 million barrier.
I also got a higher score in DFK BL with B-Strong last week, somewhere in the 470 billion range, I think (it's on the xbox live leaderboards). I do enjoy that mode but Stage 5 is such a pain, I'm not sure I'll devote enough time to it to clear it. We'll see. I've been dabbling in a variety of other games as well, but Dodonpachi Saidaioujou will be released tomorrow, so I imagine when my copy arrives (hopefully early next week, if not sooner) I will focus on that, and if the scoring strikes my fancy, I'll play it for a good amount of time.
