33m or so...I swear that learning how to full chain 1-2 is a part of elementary school.
Tried a random run with B-L, 30m.
1 bomb in st3, perfect up to the very end of st4 where I derped twice, one death on st5 and 2 more on st6.
The only thing I remember in this game is that at 1-4 when the blue spread cannons appear, enemies charge you from the left, then from the right.
The rest is complete sightread >.>
