congratulations, Azinth! Welcome to the team :p (not the Donpachi team, yet, though..)
I'm liking to play the latter stages of Gallet, more medals, meaning more points, they're bunched up too, meaning that they'll be easier to spawn/pickup at the right times, and less worries about having to collect them all (and each collected medal awards the same amount of points at the end of the stage, so picking them up is good). Also, more enemies to destroy and lots of power items (2000 points if you're full) too.
