Good enough for 7th place in the day 1 ranking. There's not much to scoring beyond shoot everything, destroy the Battleships & their escorts as quickly as possible & don't crash. You can definitely earn some more by intentionally slowing down for the zako rush areas but I just zipped through to make sure I had enough energy to finish the stages, rather than start over (again). There's some high scoring enemies just after where I run out of time so reaching there is probably better than purposely slowing down elsewhere in this mode
