Why are you people still not playing Armed Police Batrider? 
my personal landmarks on this game were reaching Grubby on Special Course (I felt that Black Heart mk II wasn't as dangerous as the first, yet I felt that the first Black Heart in Garegga was more difficult than Batrider's..), and reaching 4,400,000 points on Advanced (died on Bashi mkII, using three blue Car Pets). That was before attempting to make more use of the aura attacks and boss milking, and since I don't know how to do them properly, now I'll restart right after messing up on the first stage..

(so, I won't practice the other stages as often, if I can't get to them)
I still haven't thought of a proper team selection (in the sense of, do other ships have better potential?), so I feel clueless, just like trying to figure scoring in Touhou games (where to graze, when to try to activate borders, etc..).
