I'm off from work this week, so had some time to attempt improvements on some scores. This credit I managed to loop the boards for the first time on hardest difficulty...had the typical meltdown deep into the game (I think I actually lost 3 or 4 lives on one screen), so this probably should have been 6 million, but it's still a big PB.
